The most likely reason the compressor is not coming on is because you are low on freon. The low pressure switch will keep the compressor from cycling on because damage to your compressor would result. You can jumper across the low presure switch with the engine running and A/C turned on, ( for short time only) this will provide you with question is my compressor clutch good, or am I just low on freon. The AC compressor relay switch may need to be replaced
bad alternator or ground to ac compressor
most likely it is out of freon
Turn the compressor off.
The ac compressorThe ac compressor
For residential equipment it is 24 volts
Check the Freon pressure first. The AC compressor will not turn on if the Freon pressure is too low.
the clutch on your A/C compressor needs to be replaced.
the ac belt or the compressor bearings are going bad
IT should turn freely when the a/c is not turned on.
If it has AC assist and the compressor is shot, cut the belt or disconnect the defrost from the compressor.
Chances are, your AC compressor pump is starting to tie up.
That depends on what you're trying to do. If you just want to make certain it doesn't turn on, unplug the clutch wire at the front of the compressor.
It is on the top of the ac compressor.It is on the top of the ac compressor.
The AC clutch is on the front of the compressor where the belt rides. When power is applied to the clutch it engages to turn the compressor. It is basically a magnet a/c compressor clutch is the ound thing on the front of the compressor with pulley wheel attached. this clutch is an electro magnetic clutch that when electricity is supplied, engages so as the a/c compressor is driven ,which can then pump freon thru the ac system
Yes just as long as you do not turn on the a/c..............
The ac won't work without it and there is no reason to- it freewheels anyway until you turn it on.
If the AC compressor is engaging it could be the heater control valve is stuck open. If the AC compressor is NOT engaging you probably have a problem with the controls, a sensor or the compressor.
AC Compressor has died and needs replacement. The compressor will not turn therefore building pressure in the low side.
A lot of vehicles will activate the A/C compressor in 'Defrost' mode. Either Bi-Level or defroster will turn on the A/C compressor. I know in a lot of GM vehicles, even just the floor selection will turn it on.
Turn off the defroster.
Very likely that the ac compressor is locked up and the belt is slipping.
check fuse or relay in underhood fuse box,
Yes. The serpentine belt will still go around the pulley and turn the compressor, but with no power to it, the AC will not work! Another option is to get a new belt that completely bypasses the compressor, but that may be more than you are willing to tackle.
When you turn on the AC, check to see if the compressor is running. If the compressor clutch is not engaging, it might be as simple as low refrigerant level. Automobile AC is not like a home AC. Since the compressor cannot be sealed, the seal always leaks a little and you need to occasionally add a little refrigerant.
when the AC is on it puts more stress on the engine cause the engine has to now turn the compressor. which in turn adds more heat to the engine.
