This morning I drove to dr appointment and H2 is fine. AC was blowing.
11 hrs later, I am going out and I notice the ac isnt blowing.
I can turn off ac and hear the clutch disengage. I can turn up heat and hear something behind dash moving.

I *think* I found the 40 am fuse for the blow and it doesnt look blown

I dont see any errors on dash


Ok, where do I begin?

 

Others have reported the relay next to the blower motor overheating. Another had to have his controller reflashed. Read through this: https://www.hummerforums.com/forum/h...roblems-36995/

 

i had this happen to me last month in the middle of the road. After much tension i asked my daughter to kick the lower passenger dash area and it work till now. I know the blower module it located in that area thats why i asked her to do so as a last and desperate measure haah....and luckily it work...

 

Yeah, I thought I had luck as it started to blow again the just went slower and slower and slower until it stopped. I brought it to the dealership and the the blower motor was shot. They got me for $1000....
Bah.... whatcah gunna do?
Bright side is now it is fixed and blowing snow out in the vehicle (lol)

 

here is the link to the resistor and blower motor on amazon .

it only takes less than 1 hour to install .... for less than 200$ ... since we dont have a airfilter water makes its way down to the top of the blower motor and eventually the motor goes bad and takes out the resistor too ... this new resistor from amazon has a newer circuit board and last longer than the factory one for alot less ...
