Hi every one this is my first post as I am new here. I own a 04 Yukon Denali and never had a problem before with the air springs leaking no messages on the dic until the last snow storm we had here in Howell nj I left the truck in my driveway covered with snow which then turned to ice and after a week like that I started the truck and noticed a messege on the dic saying to service the ride control and I don't hear the compressor anymore however the truck was still fully drivable it didn't sink down as long as I didn't put anything heavy in it until my wife used it and put people in it and it sunk down in the rear and being the compressor won't come on now I won't drive it until it's fixed . Has anyone ever had this happen ? Is it an expesive fix ? My thought is a fuse but I can't find one for the compressor and don't wanna pull every one can someone tell me where it is ? Any info is greatly apeaciated and sorry for the long post ! Thanks stevem
