So a few weeks ago the blower motor stopped working all together (2007 H3) and wouldn't work at any speed. I thought a fuse might be blown so I checked and found a fuse labeled heater switch that was blown. In the manual there are numerous fuses that have something to do with climate control. Anyways I was late for work, couldn't find a spare and figured I'd replace it tomorrow. On my way home from work it suddenly started to work again. Obviously that fuse wasn't the problem but I replaced it anyways. So now the blower works when it feels like it. Anyone have any ideas as to what the problem could be?

 

Possible the blower resistor and wiring.

 

#1 question...
Have you had the GM blower motor resistor recall done yet?

 

Yes the recall was done. I thought that when the resistor starts to go it usually doesn't work on one speed. This works on all speeds when it wants to or none when it doesn't.

 

Plug to resistor, might be burnt, under glove box in passenger side, pull out plug to resistor, check if everything looks fine.

 

What was the problem?

Do you see the problem when you dig up OLD THREADS? You are talking at people long gone. READ: Old Threads/'Necro-Bumping'
