Having problems with your 1991 Buick Park Avenue ?
There's a small pump looking device under the hood between the air filter and the washer fluid container and this thing keeps coming on. can you tell me what it is?
It is called your Dynaride...it is a pump that supplies air to the rear shocks to keep the vehicle level. Makes sure that there isn't any leaks at the rear shocks, but for the most part this is normal.
