I have a 2003 Tahoe and for the last few months whenever I start it I get a message saying Rear Access Open. This problem is somehow related to my dome light and my rear wiper which also don't work. I've spent a few hundred dollars thus far for basically labor and because the problem is intermittant, I'm back at square one. The mechanic I took it to said it had to do with a bad module in which he suggested I buy a new motor for my rear wiper???? It made no sense to me??!!!?? Anyway, he seemed to trace the issue to the rear hatch and he was able to make the problem go away for a couple days by tweaking the circuit board as he put it. The rain season where I live is now here and the fact I have no working rear wiper sucks! The dome light not working when the doors open also annoys me. Has anyone ever heard of such a problem??? Any help would be greatly appreciated! Take care!
