The fan speed dial works, but it seems that I can't change the temperature. Likewise, the AC button light will not turn on, and it won't actually turn the AC on. Also, the two buttons to switch between recirculate and outside air don't respond or light up. And the button for rear defrost has the same problem as the AC button. No light and no function. Any information, or assistance anyone could pass my way would be very useful. Thanks! kev2 Veteran Oct 5, 2015, 9:25 AM Post #2 of 4 (1328 views) Re: 09 Optima Environmental controls not working Sign In is there a remote starter? check fuses - ALL. is the ck eng light on (CEL)? jrswift1979 New User Oct 5, 2015, 10:00 AM Post #3 of 4 (1324 views) Re: 09 Optima Environmental controls not working Sign In Thanks for your reply! There is no remote starter. And there is no check engine light on. Someone else suggested testing the fuses. Which I plan on doing when I get home. Someone else had also said that it might be a faulty control head. But I am willing to try anything, if I can fix this myself.

Of interest that seems rear window defroster also on same fuse or at the same time? It a hatch window especially see if you find a blown fuse if that has been damaged. Remember almost all RWDs are like a decal ON the glass not inside near impossible to fix well, T   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
