Question about 1991 Buick Park Avenue

Air Ride on 1994 Buick Park Avenue

I believe that my compressor is going up on my Park Avenue. Just recently there was a clicking sound coming from around the compressor area under the hood. It was slow at first, clicking maybe once every 10-20 seconds. Now it clicks really fast and is easily heard going down the road. Sometimes it clicks and sometimes it doesn't. My battery died twice recently and I believe that it is because the compressor is trying to run almost constantly. The compressor does kick on and level the car rarely. I am wondering how to unhook the compressor so I can stop this problem.

I had my battery and alternator both tested and both tested good.

You can unplug it right at the pump...the only problem is that the rear end is going ride low and you will notice a steering power, and some bottoming out in the rear. The best thing to do is see if that shocks themself might be leaking and replace them if they are since eventually this will damage the pump. Sometimes it will just blow the fuse, which brings me to my next point...you could just pull the fuse in the fuse box to shut it off.

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.

We just purchased a 2003 park Avenue buick and noticed a constant buzzing sound. What is it? Thanks. S.s.


You could be hearing the air compressor for the air shocks running. This would indicate an air hose cracked or fallen off the shock.

I doubt it has anything to do with the transmission.
When the brake pads wear most have a wear sensor that drags along the rotor.
Have you pulled the wheels and checked the brake pads ?

95 Park ave Ultra AC compressor at clutch is rattling and loud noises. It does not work and I do not want to replace. Ideas on how to stop the noise?


Hello:You might try putting a 1/2 inch diameter rope around the pulleys by passing the a/c compressor. Go to a parts store have them help you measure the amount of rope it took to go around the pulleys. It will be kind of a hit and miss attempt but much cheaper ( shorter belt verses a compressor) Once a clutch pulley assembly is tore up there is not any repair.

Air ride compressor runs when i shut off engine car is level no change in height when running just runs all the time had to unplug it to get it to quit but ride is still ok does this mean that the...


There is a switch under the rear of the car that actuates the compressor when the ride height falls below a preset level. The switch could be out of adjustment from being hit with road debris, causing the compressor to run al this time. Or there could be an air leak causing the air shocks to be constantly trying to raise the ride height. If there is an air leak, the back of the car would be much lower than the front, but still maintain ride quality.
