I didn't know there was a control module. Just the air bags/springs, lines, compressor/drier assm., and relay....
Anyone else?

I just replaced both my airbags and all 4 shocks. I adjusted the ride hight sensor so that the rearend would sit up another inch. I also replaced the drier on the air compressor. If you need to buy new airbags get them at strutmasters.com. The dealer wanted to charge me 320 each plus 120 for each solenoid and 100 for the dryer. Strutmasters i got the airbags for 110 shipped each, got to use my existing solenoids, and i got the dryer for 45 shipped. It even came with all new orings for the solenoids. Did not know about a control module. Will have to look into that.

The control module is above and behind the radio. You need to remove the front part of the dash to get to it. | |
