Yes, the windshield defroster will turn the A/C compressor on.
bad alternator or ground to ac compressor
most likely it is out of freon
bad motor or capacitor
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.
Low or no freon will cause the AC not to work. Also if the clutch on the AC compressor has failed, or if the compressor itself failed.
The a/c clutch will not engage and the compressor will not come on.............
the clutch on your A/C compressor needs to be replaced.
the ac belt or the compressor bearings are going bad
A remanufactured engine for your vehicle would not come with an AC compressor. Your original AC compressor would be reused or replaced with a new or remanufactured compressor if needed.
If it has AC assist and the compressor is shot, cut the belt or disconnect the defrost from the compressor.
Buy a new one stupid.
check the cycling switch.
Chances are, your AC compressor pump is starting to tie up.
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
IT should turn freely when the a/c is not turned on.
There can be a couple of reasons due to which the AC compressor of your car might seize to work. First of all check the wires leading to compressor and the fuse switch. Next you have to check if the compressor holds enough gas for AC to work. Also, check for a leakage in steel pipes that circulate the air.
Yes just as long as you do not turn on the a/c..............
check to see if your rad. fans come on when you turn on your a/c the compressor will not work if the do not come 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.
The ac won't work without it and there is no reason to- it freewheels anyway until you turn it on.
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.
