i dunno if this will fix the prob or not but there is a junction box directly behind our climate controls .  the easiest way to get to it is remove the stereo and the lower section of the dash on the pass side around the glove box . there is 1 10 mm bolt holding it to the dash frame. one conector . there is a button in the middle of the plug on the drivers side of the plug push and wiggle the connector out of the box. undo bolt and remove the box. this is a dealer only part couldn't find it on autzone web site didn't try any 1 else though. it may be you're problem if ot this then it will be the wiring has been chaffed or switches them selfs
