a/c not cooling?

Hello,


It sounds like you may have a blend door actuator that is not working correctly. This guide will help us see whats going on so we can get it fixed for you. Do you know the pressures?

Please run down this guide and report back.

I have filled it with a recharge a.c. machine from my brothers shop actually he filled it and the pressure is the same on both the high and low I believe it's 80 on both

If the pressures are equal on both sides the compressor has an internal leak and high pressure is bleeding into the low side.

The compressor has been changed it brand new

If the compressor is new, you may have a blocked TX (thermal expansion valve) did you replace the receiver dryer and was the comp changed due to an internal failure that may have deposited any debris in the system?

Expansion valve has been replaced and dryer compressor was replaced because we thought it had an internal leak but it didn't

Sounds as if you have a blend door actuator that is not working here is the location so you can check it out. Check out the diagrams (Below). Please let us know what happens.

I didn't even notice the passengers side was cold so the system is working I got a new actuator and installed it now it works like it should that s for helping me with this.

Glad you could get it fixed, that kind of problem can be tough. Please use 2CarPros anytime we are here to help.

Yesterday a/c was sporadic and now out completely. Engine temp light flickered on a time or two later on before I stopped driving it all together. My be leaking some fluid. What could be the problem? Thanks

You probably have an engine overheating issue which will make the AC not work check out this guide to see if you can find the problem.

I had the radiator replaced that fixed it thank you.

why does the air conditioner blow hot air?

It sounds like it is low on charge. This video will show you how to charge the system.

Please let me know.

Air Conditioning problem 4 cyl Four Wheel Drive Manual 106000 miles
----------------------------------------------------------------
The A/C on my car is only blowing hot air. I have fully recharged the system with refrigerant, all fuses inside the vehicle and engine compartment have been checked-What have I missed? No repair manual is available for my vehicle. Please help me out? If it is a high pressure switch, where is it located and how do I change it?

Hello,

I don't think it is a pressure switch issue, it sounds more like a temperature blend door actuator has gone bad.

Here is a guide that will show you what you are in for when changing the actuator out.

Here is the way to gain access (below)

If it is a manual system see if the cable has fallen off.

This guide should help as well

We have taken our Sportage to a local mechanic because the a/c doesn't work. They said it was the control head and $500 later still no ac. Then they said it was the body control module. We took it to the dealership and paid for a diagnostics. They said it is the duct sensor. The part is $25 but they want to charge $900 in labor. My husband would like to try and replace it himself. Do you have a set of instructions?

There is no listing for this sensor. The name is most likely the issue. We need more info on the exact name of the sensor.

Did you ask why so much labor??Most likely the dash has to be removed to gain access and that is why the labor is high.

Yes, they said it's because the dash would need to be removed. The dealership called it a duct sensor but I've also seen in online as a evap sensor.

Here is the link to the part

Yes, they said they would have to remove the entire dash and put it back.

Originally when turning on the A/C or heating in my car it would make a noise.. like the fan had some issues or something.. but the noise always stopped after a minute or so. NOW, of course with summer arriving, I am getting nothing. No more noise, no more air coming through of any sorts- hot or cold. My guess is it has either something to do with a motor or a fan or who knows. I know nothing about cars and just need to know where to start on this issue!!

check blower motor fuse in passenger compartment fuse box .. check the resistor located on blower motor housing and check wiring, and the actual blower motor ... I suspect the motor needs replacing from your description of the fault !!

I have noticed that after about an hour of driving, the AC slowly starts to get warm. At first it works great, it is so cold I have to have the blower on low and slowly I will turn the blower up to full speed and it is still warm. My temperature gauge on my dashboard never moves to indicate that my car is overheating. Why does my AC get warm after an hour of driving?

Could be no/low freon, compressor, or the air blend door is sticking or the air blend door motor itself malfunctioning

I have noticed that after about thirty minutes of driving, the AC slowly starts to get warm. At first it works great, but after driving a while it turns warm. My temperature gauge on my dashboard never moves to indicate that my car is overheating. It has Freon. Thanks

Refrigerant charge may be low or over full, this need to be tested with a A/C charge unit. the correct level is critical and also a blocked condenser can also be a problem. flush through the condenser to make sure air flow is not interrupted with leaf litter, bugs or mud build up.

Air Conditioning problem
1998 Kia Sportage 4 cyl Two Wheel Drive Automatic

lOW SIDE =40 PSI
HIGH SIDE=240 PSI
outside temp (FLORIDA)=92 degrees (F)
topped freon off since it was not blowing cold at all; pressures read as above with blower on HIGH.
THE low side ac pipe coming out of engine firewall(evaporator) is warm, other high side pie (ac line ) is HOT to touch. What could be worng..BOTH fans come on (ac condensor and radiator fan..car NOt overheating)..
problem seems intermittent. Sometimes car will blow cold air (only when pipe coming out of evaporator(low side is cool to touch and sweating; otherwise, pipe gets hot again and will not cool car.
Both fans(AC CONDENSOR and radiator fan turn on). Car not overheating..PLEASE advise, thanks

Try fan on low doors, widows closed does low go down say to 30psi? and system blow cool? if not check temp. blend door cable may have bent if not closing then heater coer is warming air.

When the car is running and the a/c is turned on it blows cold for about 10 min then switches to just normal air temp. Could this be the compressor?
Any other ideas?

If the compressor is there any issue with me changing it then having a tech evacuate the system pressure test and fill with freon?

Thanks

It could be a lot of things like compressor condensor fan inop car overheating debris in radiator or ac condesor fins blocking air flow low on charge.Without actually checking high and low pressures ac condensor fan operation one would only be guessing as to why it does that.
