The rear shocks on my 1993 oldsmobile ninety 98 do not work.

The motor/pump was going out anyway. (battery drain). Unplugging it just killed it.

Raise it up,crawl under & remove the starter bolts

i would suggest lookin in side the vents depending on the climate you live in a field mouse or some lil critter may have got in there to build a nest....i say this because i have seen it a many times in my career...good luck!!!

DROP THE TANK

you will have to reconfigure the rear suspension, best talk to a spring and suspension shop

Did you bleed the line for air? If the break line was by the master cilinder, got to bleed all 4 tires, otherwise, got to bleed the two front or two rear tires.

If you step on the brake and feels spongy, is probably air in the lines, if it feels hard check master cilinder, if you hear an air leak, check brake booster.

Thr front will be MacPherson struts, a shock absorber surrounded by a coil spring looking set-up.


FOR THE REAR:
If you have front wheel drive and you have Electronic Ride Control (ERC), then the rear suspension has "super lift air shocks".

If you have all wheel drive, then you have struts in the rear suspension.

Does help any?

You need a blower motor resistor.

replace blower control module

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!
