The ac compressor won't engage from switch on your 90 shadow is there a relay in the system?
There is a rely on the drivers side fender. It is the second relay from the front of the car. If it won't engage usually it is that there is too low or too high pressure in the system. Most of the times it it just low on freon and a sensor will not allow the compressor to turn on.
What else can I help you with?
If the AC compressor clutch does not kick in and the relay and fuse are ok what could be the problem?
The clutch receives it's signal to engage from a pressure switch in the system. If there is insufficient refrigerant in the system the pressure switch will not close resulting in no power at the compressor clutch to make it engage.
The ac compresser well not engage when ac switch is on?
Most Likely refrigerant charge is low -- compressor will not engage unless system has proper pressure
How do you engage the AC clutch to refill the system?
You don't need to engage the compressor clutch to recharge the system. In fact, you shouldn't engage it without refrigerant and oil in it, because the refrigerant carries the compressor oil in order to lubricate the compressor. But, to answer your question, you disconnect the low pressure switch, and run a jumper wire between the two female ends of the connector.
What is the ac switch closest to the heater core on a 1990 corvette called Ive replaced the cyling switch for the compressor and charged the system butI still cant get the compressor to engage.?
It's the low pressure switch. Check the compressor wiring and be sure it is grounding. Sometimes the clutch gap gets alittle wide and has to be regapped.
How is the compressor clutch engaged on the air con system?
When not engaged, the wheel spins freely. When the low pressure switch closes, it closes the electrical circuit to the compressor clutch. This actuates an electromagnet, which pulls the clutch in to engage it.
If your AC compressor on a 98 Saturn goes out and you unplug it will your car overheat?
Unplugging an a/c compressor shouldn't effect the heating and cooling system what so ever the only tie it has to that system is the comperessor makes the fan come on when you engage the a/c switch
My 1998 Camaro's AC compressor will not engage the fuses and relay are all good Any ideas?
This could be because you have a leak in you A/C system causing a loss of freon. When there is not enough freon in your system the A/C compressor will not engage, it will harm the compressor.
Ac compressor will engage but will not disengage on low or high?
If the AC compressor engages but won't disengage, it may indicate a problem with the pressure switch, which monitors refrigerant levels. A faulty pressure switch can cause the compressor to remain engaged regardless of pressure. Additionally, issues with the AC control module or a stuck relay could also prevent the compressor from turning off. It's advisable to have a technician diagnose the system for accurate troubleshooting.
Is there a relay for the rear load leveling system on a 1996 Oldsmobile 98 Where is it located Problem is new compressor and leveling switch but compressor will not engage automatically?

The ac compressor on my 1999 Ford Taurus won't stay engaged?
You should have the system checked for the proper amount of freeon. The compressor will not properly engage if the system is low. Hope this helps.
Do the black and green wire on a 1996 Isuzu hombre's compressor lead to a fuse or relay you can jump the clutch from the battery but it will not engage without running power to it?
Thats green and black wire is the switch wire for the compressor clutch. Trace the fault back to the relay. Bridge the relay out and see if the compressor comes in, if so its either the relay, switch or fuse. If not then its the feed to the relay.The system WILL have a fuse and a relay. Hope this helps.
Where is the fuel shut off switch on a 1993 Dodge Shadow?
