Just for reference
, in case anyone has this same problem.
On my 2004 GXP
, I have this air compressor hookup in the trunk:
The button to the left actually says AIR on it, but its too sunny to tell!
anyways, the compressor was turning on as normal when the car was started (as indicated by the low rumbling noise under the trunk about 15 seconds after the engine is started, and lasting for about 3 seconds).
however, when I finally wanted to use the accessory inflator to add some air to my tire, I discovered that the compressor did not respond to the AIR button being pressed.
After taking it to Mr. Goodwrench, and spending the $100 on my x-tended warranty deductible, they had replaced the compressor unit and said that solved the problem. Of course it didnt and within 5 mins after I complained, the technician narrowed it down simply to the RIM (rear integration module).
after the 15 minute fix to replace it, the compressor and the accessory inflator now work properly! Don't be fooled into having to replace the ENTIRE compressor unit! As in my case, it was simply the RIM.
Good luck and happy driving!
