2002 Chrysler Voyager - heat works while driving and blows hot but when sitting idle at a light, the heat starts to blow cool. Once I start up again or put car in neutral and give it a little gas, heat starts coming back. Any ideas? It has nothing to do with if I have the outside air vent open or closed - same results. Same thing is happening with my 2000 Sebring. Both vehicles have over 100,000 miles on them. Thanks

Make sure the coolant level is full. Chances are it is low. This video can help as well

Air Conditioning problem
2002 Chrysler Town and Country 6 cyl 97000 miles

The air cond in my 2002 Chrysler Town and Country blows cool air in both the front and rear. It does not blow cold. It also seems like the fans should blow harder than they do. We bought the van a couple months ago and it came with no service records. I checked the freon psi and it seems to be in the correct range. I just hope it's not an expensive fix. Could it be related to an old cabin filter? Thank you so much for your help.

I found the cabin filter and it looked original because it basically tried to jump out because it was so nasty. Taking that out made the air blow harder. Still looking to take it by the local dealership on Monday to find out why the driver's side vents don't blow as cool as the rest. A/C temp overall needs big improvement.

I'm having same problems.
only driver side is blowing with warm air, rest of vent is just fine. It only happens when car is under hot sun in summer.
So, I tried to park the car under the shade when I park.
but when I drive under hot sun, there is nothing I could do, but sometime cold air come and go.. it's very strange things. My dealer couldn't find problem at all when I brought the car for check up few times. Hope you will have luck to find a problem and be able to fix it.

The dealership ran tests in the AC system and said that the condenser has a leak and needs to be replaced. Great, except for the price tag of $718. It's at a smaller local shop today that will do it for $300 (with a used condenser from a junk yard). Fine by me as long as it cools. August can be warm in NC.

In my 2002 Chrysler T&C the driver side a/c does not blow as cold as the passenger side. The passenger side is very cold and driver side is tepid. Is there some type of actuator or sensor that directs air temperature from the system and is it a quick fix or can I do it myself?

Thanks.....

The only thing that adjust the temp is called the blend air door. It is located near the heater core and opens and closes based on what you need, heat or AC. You could check that to see if it is sticking.

Let me know what you find.

Hi:
It sounds like the switch has shorted. You could check continunity through the switch with the switch on and off to make sure it is the problem.

Let me know if you have any questions.

Hello,

Well ummm.... could be low on freon.....

With engine off look under hood for the A/C Compressor. Notice the front of it. Now start the vehicle with A/C off and look at compressor, noticing the front of it. Now turn on A/C and look at compressor. Does the front of it kick in and out frequently. If so then most likely you are low on freon.

I have an 01 t&c thet hade a bad a/c compreser (locked up) I replaced the compreser and the condencer and flushed the lines,evaced the system and rechard with new R134 now it dose not get cold in front and only cool in the rear,the cooling fan will not turn on some times and it will pop the high presser valve when the fan is working the high presser is 250-300psi with the low at 20-35psi. Any help is greatly needed?

You have a blockage in the system, probably in the reciever drier...the desicant bag may have collapsed, and or the old compressor, if it had teflon coated parts may have caused "Black Death" in this case a pancake filter must be installed the systems recharged and run for at least 1 hour, then evacuate, remove filter, replace reciever and orifice tube and recharge.

Checked for Freon was really low pulled vacuum and checked for leaks and refilled per manual! after doing this it was driven five miles and it stopped blowing cool air check pressure it was great, but the compressor was not engaging. so I checked the relay when I depressed it down it would work and blow cool for a minute this van is a LXI Need help!

It sounds like you have a fuse (there are several) that is out or a pressure switch is not working. Here is a couple guides and diagrams (below) to help us do some simple tests to figure out what the problem is.

There is a drain to collect water from the ac. NOTE: The AC works on defrost. The drain is most likely plugged and not allowing the water to exit the vehicle. If you open the hood of the van, check the passanger side of the firewall. I believe you will see a black rubber hose with a 90 degree bend down. Move it around to see if anything is plugging it.

Let me know what you find.

Electrical problem
1998 Chrysler Town and Country 6 cyl Front Wheel Drive Automatic

98 CHRYSLER T and C a/c lights flashing on cluster. I tried the calibration test but end result is a/c and recirc lights flashing twice then a third time with rear wiper light flashing all 3 together and it continues w/o end. whats the next step?

Our 98 T & C had the same problem. While we had it at our local mechanic for a seperate issue they fixed the blinking light problem as well. They said Chrysler told them what to do to stop the blinking lights. I am not sure what was done but I can try to find out for you. In the meantime check the TSB's (Technical Service Bulletins) or call Chrysler corporate customer service. I'm pretty sure it's a quick fix because they didn't even charge us to do it but you will probably need an OBD II scanner to fix it but again, not sure. Good Luck

A/C not blowing cool air, somewhat warm but not hot. Mechanic topped off freon and still same. A/C will not turn on immediately upon starting either. Two lights are flashing relating to the wipers, there are 3 lined up vertically and the top two are the ones flashing approximately 5 minutes after starting before they stop. Not sure if this is related. Possible relay problem?

Also, read on another post with similar problem on a clunk sound when driving slow over a bump, 5-15mph, on the front end. Any solution to this assuming its a common problem with this vehicle. Submitter had mentioned something about a possible control arm bushing.

Pressure switch could be bad for the AC, I have seen this before. EASY to replace.

I'm willing to bet it is your sway bar bushings where they are bolted to the crossmember, these are always the culprit in chrysler minivans.

as far as the clunk goes, my 96 did the same thing and it was the sway arm bushings that I had to have replaced. Now no more clunk.

The clutch is not engaging. Disconnected the clip which seems to go to the compressor and checked with volt meter and there is no voltage present. I measured the resistance of the coil and found a value, so I connected a cable with a fuse and fed 12 VDC and the clutch worked and I had cold air for a few minutes, until I observed that the fan was not working and I chose to disconnect the cable for fear that the pressure would increase. what could be happening? I checked the clutch fuse (15 Amp) and the clutch relay (with external 12 VDC) and they are okay. What condition is missing for the clutch to work, just by turning on the cold air button? Thank you

Good afternoon,

I attached a wiring diagram for you. We need to do some testing at the relay to see why it is not engaging.

thanks for your answer. I have 12VDC at the base of the relay, I checked between them and with respect to the negative of the battery. The weird thing is that when I connect the relay, I don't feel/hear the coil activate, like when I feel it when I testing it with an external 12VDC source (I also externally tested the state change from NO to NC). Is it possible to "lose" the voltage when connecting this 78 ohm resistor relay? Another question, shouldn't the fan work, as soon as I press down the cold air button? I replaced the relay with a new one and the same thing happens. the coil is not activated.
Thank you

Okay, with the key on, there should be 2 wires that have power. Check the terminals for this voltage. They both come from the fuse block as in the diagram I sent you.

No, black lead to good body ground. Then probe the terminals and make sure you have 2 terminals that have power.

I checked voltage with respect to two different body ground and the result is the same. I checked for resistance at a point that I believed there would be continuity.thanks for the support.

Do not worry about resistance.

Okay, can you see the color of the wires for the terminals? One of the wires with no power goes to the ECM for a ground and the other goes to the A/C clutch.

Use you ohm meter and test the wire from the compressor to the terminals in the relay. When you find that wire, jump the wire from one of the powers to that wire. The compressor should come on.

I have a 1996 Chrysler Town & Country 3.8 LXI with 138,000 mile. The AC blows warm to hot air all the time. Do I need to recharge it or is it another problem. My belt runs fine and doesn't wear abnormally so I don't think it is the AC pump. If it does need a recharge which one do I need to get and how do I do it safely?

You will have to get the AC freon level checked.

If you are not familiar with AC systems, have it done at an AC shop. The compressor could be bad, the AC clutch is may not be working and you have a leak somewhere.

Freon is R134a, and while you may be able to recharge it yourself, the freon will soon leak out and you will be back to square one.

Okay, i did that test yesterday, but i was not very specific when i explained it in my first story; the compressor works, but it exceeded the pressure (I think I add extra of gas in it) and a green liquid came out of the head (maybe the previous owner added it to detect leaks), that's why I stopped the compressor. replace a couple of o'rings and I left it ready to be able to detect why it does not activate automatically. In the last voltage measurement I made, I felt that the relay coil was already activated. I insist should they turn on the fans when I turn on the cold air conditioning?

thank you for all of your help.

The fans will come on when the high side gets to around 150-200 pounds.

The fact you overcharged it is no good.

You need to recover the freon and start from the beginning. Evacuate it for 45 minutes and charge it with exactly the amount needed.

okay, just yesterday with the help of a friend who has the equipment, we evacuated and added enough again; When the over pressure happened, it was the only time I saw the fans turn on.My problem is that the cold air conditioning does work not automatically... in your skill what other factors could prevent this from being achieved? why automatically the voltage does not come to energize the A/C clutch?

Thanks again

The pressure switch needs to be checked. Did you check the voltage to the switch?

I attached the diagram of the pressure switch. Check for the reference voltage to the switch.
