My air conditioning stops working while I'm driving.


This is odd...will it do the same thing if you just let the car idle for an extended period of time or just when driving? The reason I ask is that the compressor has an electro magnet centrifugal clutch that makes sure that the compressor always spins at the same rpm regardless of your engines rpm's ...if that makes sense. If the clutch has failed, you will be forcing freon through or across the reed valve gasket since it's a closed system as the pressure will have no where else to go. If it works fine at idle you can either rebuild the compressor or get another depending on your skill level. Hope this helps

A/c clutch is not kicking on in 1994 E320


How do you know the freon charge is not low ?
If the system is full, you should be able to jumper the relay and make the compressor clutch engage.
If not, the problem could be the low pressure switch or the clutch.

1995 chevy silverado c1500 air conditioning unit blowing hot air - what to do


There are 2 pressure switches on the refrigerant lines. Pull off a connector and short the wires on the connector. If the clutch engages then the pressure switch is bad.

2001 XL7 Airconditioning is not working only air not cold.


Is your compressor kicking on? If it is not kicking on chances are that either your compressor is bad, you have a bad switch, or a blown fuse. Another thing to look into is whether or not your A/C unit is fully charged with 134a coolant. If your unit is not fully charged it will not blow out cold air. I hope this helps you out.

A/c compressor clutch will not engage


In this case, I would suggest that the low freon pressure switch has activated and prevents the compressor from running and damaging your system in your 15 year old vehicle. To prove this, find the switch and short the switch out and see if the compressor kicks on.

How do you fix this? Get the system recharged. Also have the mechanic check for leaks. The freon escapes somehow ...

Thanks for your question today.

The a/c clutch wont engage


Did you try jumping where the Clutch relay plugs into the fuse/relay box ? Pin 87 & 30 are the compressor clutch coil power supply . If you look on the bottom of the relay you will see four set's of numbers 30 & 87 , 85 & 86 . If you take a piece of wire an jump 30 to 87 this will send B+ voltage to the clutch coil engaging the compressor . Is the PCM turning on the relay ?

My compressor will kick on and off at random, air is ice cold too


Just change the clutch, its not that hard of a job. If you change the whole unit you will have to vacuum pump the whole thing down. And replace the freon. Just change the clutch. you might want to check the saftey switch that stops you from running with out freon.

The air on my 1998 chevy suburban blows but it doesn't get cold. I put free-on in it. It only took a little. The compressor will turn manually & will not kick on. fuse ok. electricity in harness ok....


Probably the electric clutch of the compressor is not working. This is the part that uses the power generated from the drive belt to drive the compressor. Normally if this is working, you would hear a sound in the engine compartment once you turn on the ac. Otherwise you may have only the AC blower spinning. If they check out OK, the thermostat may not be working. Your AC will not engage because it may be getting the wrong signal thermostat.

Air Conditioner works intermittently


It could be your low pressure cycle switch is going bad. Check the connection to the switch and it's is located on the A/C Accumulator. The other thing to check is the A/C relay and that is located in the glove box. There is a panel in the glove box that say's relay, there is three relays in there and one of the out side relay's out of the three is the A/C. can not remember which one it is. The middle relay is the fuel pump and the other one is the third break light. Switch the two out side relays and see if your A/C get's better. the other thing too is if the R134a is just a little low, and needs to be topped off. Good luck and hope this helps. if your going to try to recharge the A/C system your self, keep in mind not to over charge.
