good morning i have a 2007 H2 and the module just quit yesterday while picking it up at the detailer i have no lights nothing when i crank the vehicle it flashes real quick then back out, checked all the fuses and did the reset procedure im lost do i need to buy a new module i really could use some more thinking caps before i make that purchase thanks and have a great day!!!

 

try adjusting the dash dimmer first maybe its set to off unless its just the climate control thats affected. in that case it is most probably the climate control module or the connectors on the back of it might not be seated properly or light corrosion.

 

thanks man just got it out and ordered a new one be here in the am 241 bucks later lol! thanks for your time !!! and now my information center that reads the mileage has went out as well one thing at the time I reckon.

 

Too late for "more thinking caps". Find a new detailer.

 

that is also controlled by the dimmer switch. or the cluster needs a rebuild.

 

ok got it all working but the blower motor for the air want work trying to check blower motor fuse is good . and got it working this morning with original parts haven't gotten new controller yet

 

check the blower motor module. the blower motor goes connected to it.

 

it was the motor itself I replaced it earlier thanks for the input now to replace the sunroof motor lol!!

 

Just to be clear, all your issues started, after leaving the detailer?

 

maybe they used a fire truck to hose the inside down HUMMERZ?
