Location of air ride pump

I have a 98 buick park ave. I had the rear air shocks replaced, then the air pump wouldn't stop running, so the mechanic unplugged it. that is fine when the car is empty, the car drops too low when loaded. i can't find the air pump to replace it, is it fairly easy to change out?

The airpump is located right above the exhaust. Its very easy to have it removed. I have had many problems with the air ride systems. Check to make sure the air lines werent rubbing against the tires...the compressor can be picked up used at many salvage yards for 50 bucks, but if te compressor is lifting the car, then there could be other issues.

It should be right under the hood (follow the small air lines to it)
If it is not there , then they hide them under the rear quarter panel on some models.
Follow the lines from the shocks to it .

I would recommend going to and taking a look at our conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car. Airbags and compressors are constantly having to be replaced. Also something alot of people don't know is that theses air suspensions are not meant to be in temperatures above 90 Degrees or below 40 Degrees. That is most of the world. The temperature will cause you to replace alot of bags. and typically when your replacing a bag you are going to have to replace the compressor to because the bag had a hole or small crack in it causing the compressor to over work and it will die. I posted the link below so you can take a look

I hope I was of some help

Good Luck!!!

Right rear air ride shock leaking bad want to know if i can raplace with regular shocks

Yes you can replace with regular shocks. You will want to remove the fuse so the pump no longer runs and you will be OK.
Good luck.

Falty air compressor

It could be in one of two places. They did mount an air pump under the alternator, (looks like the air pump for pollution control or it could be mounted near the rear axle if it is an electric one. I am not sure which one you would have so jack up the rear (safety first, use wheel chocks) and trace the air lines off the shock back to the source. I hope this helps you and good luck.

Air Ride on 1994 Buick Park Avenue

You have what is called a height/load leveler switch located on rear axle of vehicle .Check to see if the arm (which moves and kicks on compressor when ride height is low) Is connected and moving freely..You then might want to make sure that the air supply lines atatched to air shocks or air bags are not leaking.. If all checks out fine and you decide to disable compressor you can do this by unplugging harness that connects to compressor...And then you can manually adjust your ride height by adding air to the valve on compressor (it resembles a tire valve stem) this will adjust your your ride height and you can let air out at same location if lower height is desired.. This is a little inconveinient but will bypass automatic system as you requested.
