2006 GMC Sierra 3500 Q&A
2006 GMC Sierra 3500 Question: 2006 GMC 3500 Sierra LT. Heater Blower would not turn off.
Even with ignition off and Key out the blower motor runs. Went to local dealership they say it is not uncommon and I need a new Blower resister module. So I get one and replace it. Still have speratic functions and now nothing. Control panel works fine all fuzes good. no blower. no heat. what am I missing? - kinlee01
I THOUGHT GM WAS DOING A CUST ASSISTANCE ON THAT ISSUE. WERE DID YOU GET YOUR RESISTOR AND IS IT CORRECT. - globalhelper
Check for proper voltage to the blower resistor to find out if the problem is before the resistor. If you have the proper 12 volts to resistor then check the voltage at the blower motor. This will very due to the seed selected on HVAC control. You should have 12 volts to the blower on high speed. If everything checks out to blower motor connector then you have a faulty blower motor. You may have gotten a faulty resistor but being that it is a dealer part thats doubtful. - gmc4me
