I have posted this on a few GM/Chevy boards in hopes of someone being able to help me diagnose this issue.
Ever since I bought my 2003 Tahoe LT 4x4 in summer 2008, the rear air (heat or a/c) won't work. No air will come out, the blower motor doesn't seem to turn on. The dealership said they would fix it if it wasn't the A/C (which it wasn't). The replaced the blower motor and resistor and then I think they wrote me off as a lost customer because they never called me back (waiting for a part for over a year), now they won't acknowledge they said they would fix it. So I want to try and fix it myself, if I can just figure out where the problem is...
So, the blower motor isn't coming on, resistor checked out. The controls in the back seat for the rear air/radio... when you press any button the display says "OFF" then turns off after a couple seconds. I tried setting the front controls to aux or controlling it from there, still nothing. I took the front control panel down and checked the connector, there wasn't any corrosion present from moisture or water leaking into it from the sunroof.
I guess I am hoping that something will jump out to someone and they'll say "oh hey I had that same problem, here is how I fixed it!". Hasn't happened yet though. I know I am not the first ever to have this problem, but if it is rare the owner probably just took it to the stealership
