The drivers side climate control is not working properly. It will not adjust when I change it. Sometimes it does blow the correct temperature air, but then it won't shut off, or allow me to change the temp. Any solutions? Thanks.
Mine done similar, blowr vents would come on and off as it chose randomly, it was the
Air Conditioning Power Module
Part No 20956 . located close to firewall on passenger side under glove box asiest way to replace is take glov box out, 6 to8 7 mm socketscrews, bottom panel comes down remove the bulb and temp sensor wire plugs, set out of the way, once you have remove glovebox (pll straight back} and set out of way, now you can ee it in behind another electrical plug, n\but oce you remove the top screw, you will need to turn and pull up, unplug the connections on the power module and out, replace, and plug back up. put top screw back in, and test, once you verify it works complete putting glove box, and screws, the panel and screws(don't forget to plug the light ana temp sens back tighten all bolts. ((seems like tkes long time by instructions, but in reality it only took abt 20 min out and back in running) part cost 159 @ advance, but if you order on line, and use code visa you get 50.00 off, cost me 103 and some change w/free delivery if visa code does'nt work ,use FABU that's for 40 dollars off. now all works well both side dual climate controls, and steering wheel controls too.

Same problem as mine has. I just found out that it could be the LH Electric actuator, located under the driver side dash, just about straight behind the radio. I got mine in order so i do not knoe if that is the solution yet. just athought for ya.sounds like this should fix it though.

the heat door is probably stuck.that why temp light flashing
SOURCE: Dual heat - only heat on drivers side but adjustable for passenge
The thermostat adjustment control may need to be replaced. Also check the hose on the back for cracks, clogs, or missing.

Had the same problem, replaced the ambient air temp sensor in front of the radiator. Cost is like 10-15 bucks. Don't worry if temp doesn't change right away. Took me about 5 miles and then it worked great.
