Ac not working

Hello, can you see if the A/C compressor is cycling off and on? The front of the compressor has a clutch that you should see moving then lock up and start moving again.

Let us know what you see.

Yes the AC compressor is working. I can hear and see when turn on and off.

Can you change settings from floor to dash for air flow? One of the doors may not be moving correctly. Do all other settings work?

When I change floor to dash,they close and open but blowing hot air,the others settings work and blow hot air.I keep the climate control in cool.

Okay, so either the hot/cold mix door is stuck one way, there's a wiring problem, or the climate control module isn't working right. You would have to pull the climate module out and check that it's sending power on the right wire to the door motor. And another thing is this car has a body control module that's in play here too. But checking for power is where you would start with this.

Sorry I was looking at the wrong year, the hot/cold button is cable controlled. Here's a quick video I found with repair instructions:

Thank you. I will check the video and see if a can do something.I'll back to you as soon as the rain stop.Thank's again for help me.

Hello,

I pull radio and climate module and I do not see any cable,It is very difficult reach a plastic cover at there.The video I see is difference than my car. Mine is Dodge Stratus 2006 2.4 L 4 Cylinders VIN # 1B3EL46X26N151184. Thank you. can you give a clue please?

Okay, i pulled a wiring diagram to help figure the connections on the back of the climate control module. This car does have a body control module, that's where the signal from the climate control module goes as you will see on the diagram, so testing for power is the first step. I can explain how to test this if you have a multi-meter and are familiar with it.

Do you have separate climate controls for passenger/driver side temperature settings?

No,in climate module is just 3 knobs 1 for blowing speed,1 for climate control and 1 for air position.all of them on top of the radio.

okay, the radio will have to come out most likely to get to the back of the climate control module, can you take a quick picture of the controller for me? I have the wiring diagrams for both the automatic and manual systems.

Thank you,yes I have multi-meter appreciate if you teach me how measure.

Okay, so with the meter set to DC volts, on 20 volt setting. Set the negative lead to battery ground and the red lead is going to be for testing each wire. Make sure you have a good connection on the ground side, check it at the battery for a good reading. And you are going to back probe each of these wires with the connector still plugged in, its going to be tough because of its location, but here is a diagram of how to back probe a connector without damaging the wire insulation. And you are going to check the power wire first, just to make sure it's okay, it's going to be the red/white wire first, that should be battery voltage. Next go to the yellow/orange wire and as you're turning the hot/cold knob the voltage should should go from 12 to either 5 or 0 volts. Either way it should vary as you're turning the control knob, that's the important thing. This wires are the ones with the red arrow on the diagram I sent earlier. We'll start there for now, and depending on the voltage readings we'll decide which way to go next. Any questions, just ask, If voltage is present and it's working okay, we'll go after the climate control module a bit next.

These are the 2 connectors you should find on the back of the climate control module.

Okay, I check for battery voltage and read about 13 V. I check the red/orange wire and turning the knob read 1.17 to 10.97 v.

Is it possible the wire colors are yellow/orange? I'm not seeing any red/orange wires on my diagrams here. Anyway if that's the correct wire and the body control module is receiving a signal from the head unit, we'll next have to check the body control module and see if it's sending a signal to which ever motor is controlling the hot/cold mix

Oh, I am sorry. the red/white wire is voltage from the battery an the yellow/orange is for cool and hot Knob and is receiving signal when I turn the knob.

How check the body control module to see if is sending signal ?

Okay, I think you should start with checking the connections because of where the body control module is, it is attached to the fuse block to the left of the steering wheel. Its the silver looking box attached to the fuse panel. Hopefully this is the correct diagram. There are connections on the back of the fuse block that need to be checked visually as well. Make sure there is no corrosion on any of the connectors going into the back of the panel, and check the fuses while you're there. Let me know if this diagram is incorrect. There's a couple different designs. Going into the body control module, you should find that same yellow/orange wire coming from the hot/cold controls and be able to move the controls and watch the voltage change just like you did at the back of controller head (hot/cold button). Back probe the BCM while it's plugged in and the key is on.

Okay. I check all the fuses,they are good,check the connector to the silver box and is not corrosion,I see the yellow/orange wire and I did check for voltage up and down when I turn the cool/hot knob and work fine.I send you pictures of it,silver box is to the extreme left of the fuses box.

Okay, so next we'll check if the BCM is seeing a signal from the blend door motor, at the back of the BCM with it plugged in and key on, back probe the red/white wire. This should be a 0-5 volt signal depending on where the blend door is. So this should be varying 0-5 volts while turning the hot/cold knob. The pink/dark blue wire should be 5 volts steady.

in the back of BCM I check red/white wire and read 12 V and the pink/dark blue read 9 V.

I check this ground the negative led of my meter and other I put in red/white and same with pink and dark blue wire.If I did wrong,please let me know.Thank you for help me.

I'm sorry I was measure in the climate control module.I will check in the body control module that is locate near that fuses box.

Yes go do those checks at the body control module.

Okay,was very ridicule,but I did it.. Red/white wire was between 0 -5 About 4 and the pink/dark blue was 5 V.

Al514, what I see under the dash at the left side of the glove compartment right below the radio was a little white plastic box that was wet. but does not smell like antifreeze,smell like water.Is this a blend door?

Does the red/white wire voltage vary from 0-5 volts while turning the hot/cold knob on the controller head? This is the signal wire from the blend door to the body control module and should change as you're moving the hot/cold blend door.

Here is a picture of the bottom of the blend and mode doors. Both have a 5 wire plug, and testing at the red/white wire at the body control module will tell you if it's moving or not.

If you've found the blend door motor, you should check the red/white wire there. That's where I was going to send you next anyway. That red/white wire is going to the BCM. Varying 0-5 volts while turning the hot/cold knob.

Okay my friend,first I wish you a happy holiday.I check the blend door connector that have 5 wires,I check red/white wire and turning the cool/hot knob the voltage change.I see too wet the blend door activator,is water because not smell like antifreeze door on top of blower closet and open when I move the air speed control,I send you a picture from that door and this plastic that was in from of this door.

I believe this plastic was in the glove compartment.

There's water coming out the blend door connector ? If that's the case, then you've found your problem. The a/c drain hose might be plugged up. It's visible under the car on the passenger side, under where the firewall is located. Try cleaning the house out, it drains condensation out off of the a/c unit.

Al514,really I'm glad to hear this,I will check about the hose for condensation hold up,I see the hose in the fire wall.Tell me what I do next.You guide me in a way that I feel very confident in what you teach me,you are a excellent teacher because all this a new for me.

Well thanks, glad to help. So can you explain where that plastic looking thing came from? Since you've located the door actuator, the 5 wire plug with the red/white wire in it. You can actually take the 3 bolts out of it and bench test it. It's a little complicated but I can walk you through it. As for the drain hose, just stick a piece of wire or something up there to see if any water comes out. You definitely shouldn't have any water in those plugs or motors. At this point you can unbolt the door actuator and with it still plugged in, you can turn the hot/cold knob and watch the actuator move with the key on. All you're doing is commanding the blend door to move. Having water in that box, there's a chance that the actuator got wet and shorted some circuit out.

So there's a few possibilities as to no cold air, and this applies to if the actuator is working okay. 1 is that the blend door broke off of the actuator and the motor is still moving the broken door part. This would explain why you have a 0-5 volts on the red/white wire (signal wire to BCM). 2. You have a bad expansion valve in the a/c system causing an incorrect pressures, ( this you can not fix yourself). 3. There is low Freon in the a/c system. Technically speaking this would have to be fixed by a trained A/C technician. Special equipment is required.

The plastic I believe it was in glove comparment and was suck for the blower.The drain hose that coming out in firewall is about 1 inch diameter and 3 o 4 inches long facen down with an open at the bottom...Is this the drain hose?...I sent you a picture...is the hose just below the 2 hoses runing in paralel.

Yes that sounds correct, it's the only drain hose, make sure there's nothing clogging it up.

Okay, I introduce a very fine wire (hanger wire) ...
And I blow with my compressor to 100 PSI and to 120 PSI and no water coming out....Is any possibility water get in by the grills in front of the windshield ???
