cut back the positive wire enough to check the voltage on good wire , not just at the plug. if you still have bad voltage check the ground to see if you are getting decent continuity! if all is still no good replace the wire from the fuse block to the horn. this is not as scary as it sounds and then you'll be back on the road good luck

SOURCE: 1990 Oldsmobile Ninety-Eight Regency compressor runs when car is off.

The compressor you refer to is the air suspension compressor. It provides air to adjust the ride height of the vehicle. If you will notice by looking underneath the rear of the vehicle you will notice air adjustable rear shocks, or struts. They have plastic tubing plumbed to the compressor under the hood. There is a ride height sensor for the rear of the vehicle attached from the chasis to the rear differential. Whenever the height of the rear of the car is below the threshold setting of the sensor, the system activates a relay and turns on the compressor to raise the rear of the vehicle above the minimum height specified by the manufacturer. As the vehicle ages the air envelopes of the struts loses structural integrity and seepage, or leakage develops. Some depletion of air is normal, but the compressor power supply is independent of the key position, so the compressor can run, and will run anytime the height falls below the minimum. If the car sets unattended for several days, (or weeks) the compressor can run the battery down while maintaining the minimum height. If the system leaks too much air the compressor can burn-out trying to replenish the system. If you notice the compressor runing for an extended period of time, or running too frequently you should have the system checked for the source of the leakage. (Or you can do it yourself with soapy water and a spray bottle by soaking the air bellows on the shocks or struts, and all the lines and fittings from the shocks to the compressor) If you intend to work underneath a vehicle, service stands are mandatory! DO NOT UNDER ANY CIRCUMSTANCES ATTEMPT UNDER VEHICLE SERVICE WITHOUT PROPER SERVICE STANDS IN PLACE AND STABILITY VERIFIED WITH APPROPRIATE FORCE TO PROVE THE VEHICLE CANNOT BE KNOCKED-OFF THE SERVICE STANDS!

RElay is most likely your first cause. The second cause is most likely a air leak in your sstem not letting it fill with air completely

Check egr valve, check pvc valve, check head gasket, check air filter, timing timing out of adjustment, burned valves or leaking, cam shafts could be worn, check fuel enjectors.

SOURCE: the hood of a 1991 oldsmobile ninety will not open

the easiest way is to strip the end of the original cable and pull the cable to open the hood. if not you have to raise the car and try to reach the hood latch and open if from there.

I have a 95 isuzu holden rodeo. My a/c compressor is not getting power to it? I have changed the fuses and relays.Compressor works and blows cold air if i hard wire it? What could be my problem?


there are several switches that control the compressor
one is a low pressure switch that will stop the compressor if there is a gas leak
the next is a high pressure switch that will stop the compressor if the condenser fan stops or there is a blockage in the line after the compressor which results in too higher a pressure that will destroy the compressor
next there is a relay controlled by the thermostat that controls the compressor to cycle it when cabin temperature is reached
I suggest that you have an accredited ac specialist shop diagnose the problem as it can get costly

1994 chevy 1500 ac compresssor stopped working fuse is good


couple of reasons
there is no gas in the system and the low pressure switch has stopped the ac compressor
there is too much gas in the system and the high pressure switch has stopped the compressor
there is a blockage in the tx valve and the high pressure switch has stopped the compressor
The climate control module has failed and stopped the compressor
I am thinking a leak and no gas.

My 1992 tornado trofeo back is lower then the front


Check your rear suspension. Load-leveling air suspension struts could be bad or leaking. Air suspension compressor could be inoperative. Air suspension compressor relay could be bad. Air lines from compressor to struts could be leaking, from cuts, cracks, or having rubbed through against the frame. Transverse leaf spring could be sagging.
And it's Toronado, not Tornado. Sacrilege!
