I believe the modules are very vehicle specific. Had the similar problem and it is the CCM. These do fail. I did all the reccomended fixes, it doesn't blow fuse until you attempt to change the temp. Blower fan button doesn't work, have to engage MAX button and then lower the fan. Oh well, it's 01. with 250K miles.
