The air compressor on my 2006 buick terraza won't stop running. It's under the rear bumper behind the tire. I believe it controls the level ride too. PLEASE HELP

Hey FROGGYYY,

Thee is a relay that controls the system and it sounds like it is stuck on. Locate the reply and replace it.

If that doesn't help here is the way to diagnose the system.

All the Automatic Level Control diagnostic trouble codes are displayed with a blink code on the accessory inflator switch LED. The diagnostic codes will flash after the completion of the self test. The self test is achieved by pressing the accessory inflator switch for 3 seconds. The self test will take 200 seconds to complete.

The number of flashing pulses on the inflator switch LED shall represent the number of the diagnostic code. The flashing pulses shall have a repetition rate of 0.5 seconds and each code digit shall be separated by a 1.0 second delay. Each code cycle shall be separated by a 3.0 second delay. All current failure codes shall be flashed in numerical order. All current failure codes shall be flashed until they are acknowledged by depressing the accessory inflator switch or until the module enters asleep mode. The module will flash these codes with every successive self test request until the failure is removed. The blink code shall take priority over other processes that have access to the accessory inflator switch LED.

Please let us know happens so it will help others.

Best, Ken
