After replacing the battery, the climate control module only blows thru the defrost vents. The fans speeds are OK, but to get heat, the directional vent dial must be set on the defrost setting, and the A/C works when the other vent setting are used. Neither the rear defrost or the A/C button will light when pressed. I've tried a new Climate control module with no improvements.

The only thing I can suggest is out of a bulletin for resetting the system. There is a power center near the battery with a cover explaining everything. Fuses are marked. Remove fuse M1 and leave it out. Fuse B also and if no letter is visible fuse number 1. These are 40 and 30 amp fuses. Inside in the fuse panel on the lower left side of the dash remove the fuses 23-30amp, fuse 19-10 amp. And 21 and 17 also, The last two are not in the bulletin but it won't hurt, fuse 1 under the hood is the most important, wait 15 minutes. Replace the fuses, start it up and see if it resets without needing a DRBIII from the dealer. Buy a 6-12 volt test light(here at the store) and check all the fuses before doing anything because many are hot all the time even with the key off. The website here tells you the only way to correctly test all interior and engine power center fuses. I hope it works out. After the fuses are back in and good the system should completely reset itself back like new(hopefully). If not a dealer will use their DRBIII. Ok
