Just wanted to say hi before I go on my rant, and thanks for having me.
I replaced the mode door on my 2012 GC to try and fix an issue with HVAC system going into a diagnostic mode on startup. The defroster light would blink for about 2 minutes and would not allow any function of the system. When the diag was done, then I would get AC and heat just fine, but the mode would not change. It would come out of the vents and the defrost but any other buttons pressed didn't change that. Now here is the weird part. When the van is starting there is a very loud moaning coming from the actuator, so I replaced it. It does this through out the diag cycle. When I had it apart, I could feel the cam and levers and they moved "freely" but felt clunky not smooth as one would expect. The levers do not feel like they are disconnected. When I move the levers by hand it changes the mode, but as soon as the actuator is installed I get one time that it changes then it is back to the moaning. I believe my problem lies in those levers, but I cannot find any diagram to see how they are supposed to be setup. Does anyone here have any experience with anything remotely close to what I have been dealing with for the last 2 years? Any help would be appreciated. The dealer wanted $1000 dollars to diag and fix this issue.
