Question about 2005 GMC Sierra
AC on for about one hour during trip, both dule sliding temp controls in full cold. Fan @ 4, Interior recirculation switch on. Drivers side distribution duct air goes to full hot with no change in position of temperture control sliders. Passengers side air temp. cold. Should I be changing a drivers side temp control (door) Actuator first? Or is there another way to troubleshoot the problem before I throw a part at it.
Found a good post on www.fullsizechevy.com/forum on how to replace your temperture control actuator. (search temp control).
That is a good possibilty, but before I pulled the trigger I would try this first. unhook the battery for 5 minutes, rehook it, now turn the key on, wait for 2 minutes, now start the truck and see if the doors now work. sometimes this works, its worth a try.
