04 dodge durango will not blow cold air blows regular air. Why?

Not in a specific order of importance:

A lack of refridgerant.
The compressor not engaging due to low pressure, or another fault.
The cooling fan or fan clutch not operating properly.
The climate control system not functioning.
The switch not working.
A blown fuse or circuit breaker or fusible link.

Good luck !

Hi, The air con in my 2003 Audi A6 1.9 tdi 130 is blowing warm air the air con rad is fully gassed and all fuses are ok . Thanks in advance for any advice on how to fix

The only other thing then would be if the compressor is turning, engaging, and the cooling fan working properly. You should either be able to see the compressor clutch engage, as the switch is energized, or at least hear it click loudly when the switch is energized. If it is not, then there are sensors for the low pressure/high pressure line to tell the compressor when to function, that also have to be checked.

As the engine runs with the compressor turning, one line should be hot/warm, the othe,r (larger diameter hose) should be cool/cold, if the system is working properly.

If the compressor is turning when you have the A/C turned on, then see if the cooling fan is running as well. It must run to remove the heat and cause the process to function properly.

Good luck!

When I first start jeep, air conditioner blows cold. THen it starts blowing hot, humid air. Put a can of freon in and it still does it... Please help?


Check the condenser fan if it is running when u turn on ur A/C system.
If not that will be the problem to solve, check the fan fuse and the motor itself!

Look at ur a/c compressor also, if the clutch engages when u turn on the switch!

Tell us more afterwards!

Engine temp gauge reading hot, no leaks in system. Heater does not work most of the time. only blows cold air.

Make sure there is no blockage in front of radiator or condenser coil. It seems like the cooling fan clutch may be quitting. When the fan clutch is working properly, if you turn the fan with your hand when the engine is cold, it should turn freely, if you do it after driving the vehicle when the engine is HOT, the fan would be pretty stiff and should not turn free at all. By the year of the vehicle, I believe that's where the problem is.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa!!

Replace your fan clutch, very very common problem with trailblazers and envoys. It's just coincidence that the fan clutch went out when replacing the battery.

My AC blows hot air at stop lights. It works great when the car is running on the free way, but does not work when the car slows down. Any idea what the problem is????

Have you radiator clutch fan check out, sounds like its bad, air blows through radiator and a/c condenser while driving and no air blows through at stops, will cause a/c pressure to go up and not cool.

2004 santa fe AC only blows cold for a minute or two, then continues to blow air, but no longer cold....tried refrigerant, but didn't solve the problem....Any ideas?

I would first make sure you didnt over fill the system, you may have to exvacuate the system and then recharge it, then watch to make sure the cooling fan is colling condensor, if fan is not working that may be the problem,next if fan is working i would check for power at clutch, this will tell you if the clutch is bad or if its loosing power to clutch,you should have gauge to watch the hi and low side preasure readings.

Air conditioner on 1993 gmc jimmie doesn't blow out cold air. The fan runs however the clutch on the air conditioner unit won't kick in

if clutch isnt kicking in, there only could be two things.....electrical issue(test the clutch connector for voltage, relays etc.), or low or no freon(have it vacuum tested if voltage is fine). Hopefully this helps
