Some do and some do not depending on the year, make and model but just check on the rear of the compressor and you will be able see if it does or not.
If the compressor is not turning on it could be as simple as low refrigerant level. If the compressor IS turning on, it might be a stuck heater core valve.
On the top of the ac compressor.
It may be the pressure releif on the bottom of the compressor. I do not have a turbo either and after I reved it some I got white smoke too. (from the oil in the ac system)
You have to have the motor running as well as the AC compressor turning (AC on) to circulate the freon through the system
You take a piece of gum that you have chewed since you last changed the ac compressor. Then you take the piece of gum and stick it on the end of a straw and mold it until yu feel that it is secured tightly. then you blow into the other end of the straw and the piece of gum flies off, then change your damned ac compressor.
The low pressure valve on a 93 Chevy Corsica is under the hood. It is on the larger hose coming off the AC air compressor.
Heatstrips could be on with ac
why wont the ac compressor shut off stays on on all settings
Simple, you ac does not blow cold air even though you have it turned on and the temperature set to cold.
Your compressor is going out. Probably you threw a piston in the compressor or the bearings in your clutch went out. If you put freon in before this happened you overfilled it and blew the seals.
Idle the car with the AC running. Open the hood and look at the AC compressor- is the compressor engaged? (the front of the compressor (inside the belt) should be spinning. If not, then have the AC system recharged. If it is turning, then you've got the door to a duct stuck inside the unit.
