SOURCE: Dodge Ram AC not blowing cold

By pass both pressure switches one at a time with small wire or a paper clip. If comperssor kicks on replace the swich that you bypassed.
if not it could be the fan clutch ot the compressor. Compressor runs about $400.00

You probably replace the wrong switch. I believe the high pressure switch is mounted in the back of the compressor. Pull the plug and jump it. If it works, replace the switch. I don't recommend you leave the jumper in the plug. If it the A/C pressure is to high, you could blow lines and such. Costing you a lot of money.

The ac compressor in my 2006 Chevrolet Silverado turns on and off while parked. It's blows really cold air while driving, but blows hot and cold air while parked. To hot to sit in truck while parked. ...


the problem is not the compressor but the head pressure is to high and the high pressure switch is shutting it off
You say really cold while driving but on/off when stationary
That indicates that the fan in front of the condenser is not working and the high pressure gas is not converting back to liquid
2 possible items to check
fan--fan relay fan relay fuse
and excessive gas in the system
take it to an accredited ac specialist shop and have the pressures checked
At this point I am thinking excessive gas

there are 3 switches that control the operation of the ac compressor . There is a high pressure switch that will not allow operation if the head pressure goes too high ( excessive gas-blocked system-tx valve condenser fan not working )There is a low pressure switch that stops the compressor when the gas has leaked out and is insufficient A thermostat that will not register and so will not switch on the compressor and finally ac compressors will not work unless both the ac switch and the blower are switched on. Have the system checked out by an accredited ac specialists.;l

If the car was retro fitted with R134a this was a common problem. There was a low side pressure sensor that needs to be changed. R134a runs different pressures than the r12.. When you go down the road the condenser cools off the system and the pressure drops below the minimum pressure. You need to make sure that the system is fully charged, not just cold to the feel. Both pipes coming out of the firewall need to be the same temp. this makes sure that the evaporator is flooded.
I hope this helped. Re-post if you need more info. Have a nice day and good luck.

A/C is blowing hot air. Freon is full, compressor


2006 Kia Sorento EX. I had this same problem. It started after I had the ac compressor replaced. At first it was intermittent, it would blow cold and then blow hot, blow cold then blow hot again until it just started blowing hot. Turned out it was the AC relay switch in the fuse box under the hood, I swap it out with the horn relay switch (they were the same type relay switch) the ac has been working fine ever since and the horn also works even with the bad relay switch. Go figure?
