2004 Buick Rainier Q&A
2004 Buick Rainier Question: rear air suspension
The entire rear end of my buick drops. It does not always drop only sometimes after it has not been driven. Once I turn on the car the compressor pumps it back up. It used to take hours to drop and now takes less time. The dealer said they dont know whats wrong How do I know what part it needs. - Visitor
A shock can leak air pressure,or a line to the shock can leak.Check to see that the leveling device is conected to a link that controls the signall to turn on the air pump,when the vehicle is needing to be leveled by the air pumped to the rear shocks.you may be able to find the leak with soapy water sprayed on the shocks air bag or lines from the pump to the shocks.If there be a leak any where in the system the shocks will deflate!And the vehicle will sit down!I,m not sure about a check valve in the system! - Terrance Mathews
will the outdoor temp. affect the air in the rear air suspension. (cold weather)
On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.
I'm told it will cost approximately $700 to get shocks repaired. However, a friend tells me this is totally wrong and it will cost $700 for some type of hydraulic air lift? Please help. I'm told...
Where should look for the sensor that controls the left air bag, my compressor only fills the right side. I may have a leak but not sure, is there a way to check??? Thanks for your input
