Last fall my heated seats stopped working, when spring came my ac blower worked but no ac. They replaced a fuse. Then my low oil indicator needle kept diving and the alarm going off every so often. It was annoying. They have run the diagnostic machine and not found anything. Now neither the seats heat, the ac doesnt cool and the heat when needed doesn't heat. Any fuse blows immediately when I try to turn on the ac. I'm tired of repeatedly going back to the dealer. Any suggestions? One more thing in 2003 I had a problem with the overheating needle going nuts and resetting, after replacing modules etc they found a wire rubbing the frame. would you suggest I take my vehicle to an electrical shop instead.
