95 lin town car when turning on air conditioner and the clutch kicks on in the air compressor it jerks and the jerks at the same time car experiencing loss of electricity from engine when it jerks
More than likely it's the internal overload on the compressor kicking it out.
Run your engine with the A/C on and watch the end of the compressor where the belt is. If it kicks on you will see the it start turning. if it doesn't turn and never starts turning you may need your A/C charged with freon. If the belt smokes you compressor may be locked up.
The air conditioner/compressor sits on the front passenger side on top of the fender. Remove the water reservoir and then you can disconnect and remove the air compressor. I do not know yet how to remove the air dryer as I cannot see how to remove the air lines from the dryer. I did remove the dryer from the compressor though, by removing a single screw then turning the 1/4 turn and pulling it out of the compressor....so at worst I will be able to put my new compressor in with the old dryer.
You have to have the motor running as well as the AC compressor turning (AC on) to circulate the freon through the system
Hey Bill==You have several electrical problems. I suggest you take it to a garage. GoodluckJoe
What most likely is happening is the A/C compressor has gone bad and its not able to turn when it is switched on. The burning rubber smell is probably the belt sliding across the compressor pulley that's not turning.
Most likely the air conditioner compressor is seized. When the a/c is off, the a/c compressor pulley just idles (spins freely), but when the a/c is on with a seized compressor, the pulley locks up and stops the serpentine belt from turning, thereby stalling the engine. Try it too often, and you'll shred the serpentine belt. Unfortunately, it's not a cheap fix. Expect to pay $1000- $2000 or more (depending on the situation and the shop) for replacement and repair, since you must also replace several other a/c parts along with the compressor in order to validate the new compressor's warranty. Also note: The defrost setting on most vehicles with air conditioning will also activate the a/c, so avoid using that as well if you are experiencing this problem.
Most likely, it's normal operation. Most vehicles have what's called a cycling clutch compressor. A sensor bulb detects when the system reaches the predetermined high pressure limit, and disengages the compressor clutch to prevent overpressure in the AC system. When the system pressure drops to the predetermined low pressure, it reengages the compressor clutch.
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.
You will need to check the condenser for leaks, also check the air compressor, you can check the air compressor by turning on the ac, look and see if the front of the air compressor is turning. If the air compressor is not coming on you will need to replace it.You can also check your 134a level. hope this helps.

low freon, bad pressure switch, bad compressor clutch.
