The bottom on my driver's side has gone out for the second time. The service manager had the nerve to tell me this was the first Crossfire he had heard of where the heating has failed!!!
Sometimes the problem is the element, sometimes it's just a wire/pigtail.
I believe there have been some horror stories of people having their seats repaired at the dealer.
There has been another thread about this within the last week - the attachment that is on this thread was in that one too.
The kit which is shown in the other thread (not in this on as I couldn't find it) costs about $70-$80 depending on where you buy it. I'm taking a gamble and just buying this kit as that is what went wrong last time my seat failed - the locacl dealers want to charge $85 just to diagnose the problem.
