H2 air suspension clicking compressor
 

Hi Guys and gals I have just changed out my old compressor in my 2003 hummer to the new double stage, I have used the old module from my old compressor but now when I turn the key on the compressor clicks but does not start up, do I need to reprogram the module or do I need a newer style module.

You need a module for a dual stage compressor

Once you have the right module you will need a tech 2 to calibrate the rear trim height

I have a quick question, what is the added benefit for the two stage compressor? I'm thinking of adding one if it helps with tire inflation. Thanks, RJ03
