Re: extreme air faulty
As "well duh" as this may sound, when I was in Death Valley last year and went to help another traveler that had a low tire I flipped the ExtremeAir switch and nothing happened. I must have spent about a half hour messing with the wiring and nothing. I was with Mr. Thwaites so he helped out the other traveler with his compressor.
While 4wheeling that day I had an "ah ha" moment, stopped and plugged in the air hose. Sure enough, the system was still pressurized and that is why the compressor didn't kick on. It had been a very long time since I last used it and was very surprised the system was still at pressure.
Probably not your problem, but worth checking out.
