This may not seem too urgent but I live in an area that is starting to get cold and snowy, and without a solution to this problem I don't know how I will be able to get around this winter.
I have a 2010 F350 Lariat Crew Cab Dually Diesel.
For a few months now my climate control has been acting crazy. This summer, when it would be very hot outside my truck interior would cool off just fine, but once the air temp became comfortable I would feel heat. The entire passenger zone would start blowing heat. The only way to correct this was to set the cc to dual and put the temp on 65. That would work for a while, but eventually I would have to drop it to 60 to keep it blowing cool. The driver side worked just fine.
Now, I am having the opposite problem....well the same problem but opposite seasons I guess. With the weather turning cold, the pass. side blows out heat like a champ, but the driver side will only blow out cold air. I can turn the driver side up to 90 and it still will only blow cold air. Needless to say you can't defrost or melt snow with cold air very well.
I inquired from a ford service tech about the problem and he said that the head unit, the cc center in the dash was probably the issue so I purchased one for what was of course a huge amount of money and installed it. Unfortunately it is still doing the same thing.
My question is: if the cc control unit is fine, is there maybe an inside driver side or passenger side ambient air temp sensor that could be sending the control unit the wrong temp data? If so where in the world are they located? There must be sensors on each side for the dual zone climate control to work but I have had no luck locating them.
If anyone knows PLEASE tell me, or give me another idea to try, I'm running out of time before the bad weather sets in and I would like to not freeze to death in a 1.5 year old truck.
Thanks for any help.
