Its only in the rear, the air compressor is under the hood, the sensor is on the left control arm and the air bags are built into the 2 rear struts (this system usually doesnt work on a 16 year old car the rubber in the air bags rots out and they cant hold air) Napa and Sears have replacement air shocks that fit the Park Avenue. The weaker the shocks and the heavier the load the more the compressor motor runs to level the car. There is no load leveling of the front of the car. The front has tower struts, completely independent of the rear air leveling shocks.
On a 1997 Buick Park Avenue, the air conditioner drain hose is located under the hood and on the front of the firewall. It can be easily found by following the exhaust pipe from the catalytic converter on the passenger side up to the engine bay.
Air shocks on a Buick Park Ave are adjustable to give a smoother ride. If a shock or compressor fails, the rear of the car will sag an possibly drag on low road bumps.
It should be 8 bolts/4 each. let out air. Support rear weight of car, remove & replace. You can probably use the same air lines. if not replace & route in similar manner. Air them up & you're done.
My 1998 Park Avenue stalled. I cleaned the idle air control valve (IAC) and now it is fine.
just in front of the air intake on the 92 park avenue supercharged model not sure on the standard 3.8 liter
I have done this and it works GREAT..!!!!! You just have to adapt your lines to fit the shocks.. Don't be afraid to buy your shocks and install them....as long as you have skills.
The Buick Park Avenue line is known for its smooth ride. The suspension is an air ride, giving a soft floating feel.
Check in the air filter housing.
If your 91 park avenue is like the one I have. To the left of the radio is an air duct. To the left of the air duct is the adaptive lamp monitor module. The module is near the top inside of dash.
Check the following items............... 1. A/C heater controller. 2. A/C heater controller doors.
Easy: 1) Disconnect the air hose clips. 2) Unbolt the bottoms of the shocks. 3) Unbolt the tops of the shocks 4) Install new shocks 5) When installing the hoses to the new shocks, make sure the seals are clean and lubricate them lightly with a little silicone. Now, replacing the pressure hoses, that is a much harder job.
