We all have had or will have a failed DCCV Dual Climate Control Valve fail on us. Common symptoms are hot air from one or both sides of the cabin vents regardless of what the control is set to.
Replacing the DCCV is not hard. But I don't recall seeing that we should also check the fuse that is often blown when the DCCV fails.
The fuse in qustions is one of those Micro fuses, tiny square ones with probgs. 10A I believe. It is fuse #1 in the underhood fuse box. On my 2004 LSV8, this box is on the front of the passenger side fender.
I have even had this fuse blow once or twice when the temperature control system seems to be working properly. Probably just a system glitch. If the fuse is blown you will have all the symptoms of a bad DCCV even if like on mine, the DCCV is new.
Just replace the fuse, maybe a 3 minute job and something like $1 for the part unless you buy a pack full.
Good Luck,
Jim Henderson
