when you replace anti freeze you should check and tighten all clips etc as the anti freeze is thinner

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!

Your master cyl. may not be sending the fluid to the brake system like it should.

It is a mute point because you can't do this yourself. Your system has air in it plus moisture. All that need sucking out with a refrigerant gas recovery machine to create a very strong vacuum, then the system is checked for leaks. Only then is the refrigerant gas installed by weight. Freon is the brand name for a gas that is no longer used. There is a sticker in the engine bay that tells you the weight of gas and the amount of oil. This explains, take it to a shop that does AC. https://www.fixya.com/cars/r29878326-recharging_vehicle_air_conditioner ..

The blower resistor may be going bad and need replacing. Does it do it only on one or any fan speed? I'm not sure where that particular part is located for it has been number of years I have looked at vehicles older than 18 yrs. but I hope this steers you in the right direction.

I think you could use this manual method instead.. My nephew used it to repair my car and it's totally perfectly fine now. Here's the website he bought it from. www.reliable-store.com

GM doesn't believe in making things easy. No access panel

How do you know it's surging? In any case, about the only thing that can cause this is a faulty regulator in the alternator, or a poor wiring connection (e.g. battery cable or at alternator).

Have you checked the vacuum line with a gauge? If so, how many pascal units does the vacuum line read? Vacuum gauges are around $5. Furthermore, I believe the design is sealed vacuum only system. The solenoid could be bad, but to my knowledge it is not an electrical component. A split in one of the vacuum lines could be cause of your problem. You would have to trace the all the vacuum lines back to the source to find the problem. You would need that gauge to detect a leak in the system. Could also replace all the vacuum lines on principle since the vehicle is going on two decades.

Sorry Doris. It is the transmission is gone.

On most cars in this era, the pump itself can be adjusted by loosening the mounting points at the front and rear of pump.

Behind the firewall? Sounds like you need to take your dash off and get at it from the inside.
