Hello, I turned on my heat this morning,now it wont come down off 90 degrees. Also, the air conditioning worked this summer but would not control correctly. Some buttons would light up and some wouldnt. Is control unit going bad and if so where could I find one. P.S., How do I get the cover off the control unit? Thanks in advance.

 

Try disconnecting the battery for a while. Read that somewhere in the FSM.

 

Took the climate unit out and disassembled it. Cleaned all switches with alcohol. Works better than ever. Did not cost me anything but time. Thanks

 

Congrats.....
