Hey everyone,

Im wondering if anyone has experienced this phenomenon before. We have an 03 burb z71 with rear air and radio in the center council and up in front in the visor area as all of them do. it is a quad seating setup also. It recently quit working all the time as it should.

it doesnt work using any of the switches at all but the lights come on in the rear dash. the problem is, it is intermittent. We had it turn on after about 10 minutes the first time it quit working. Yesterday it didnt work, we turned the car off, and it started up after turning the key back on. it may have went back off again after it started working, i cant remember if it was turned off or if it quit. Today, it didnt work at all for 300 miles with a turn off inbetween. I think the system was off during the shut down so that test wasnt the same as yesterdays. It didnt work after turning it on after remembering it started after a restart yesterday.

Im not sure if it works off of the same pump as the front, both sides in front are working with both top and bottom working well. I first thought fuse but since it was working intermittently it probably wasnt that, but a wire that is messed up or the pump is going out. Wheres the pump at, if it has its own? Where are the wires at for the air?

Any thoughts?

Thanks for any help or info!
Steve
