Blower Motor Problem..need Help
My blower motor in my 07 cobalt stopped working....here's what I know so far...there had been a low rumble on low that was intermittent for some time...when the speed was increased, it stopped...the other night, I drove somewhere, got out and when I came back, started the car and the blower wouldn't run. I checked the fuse but it was ok and I did notice a kind of burnt electrical smell in the car, you know, the kind of smell you get with hot electrical problems...I had had a similar problem some time ago where the dealer said that they found a broken wire when the blower had stopped that time. I looked up how to replace the blower and fan and see that they had replaced it since the assembly appears to be the screw on version instead of the molded in one. Anyway, I checked the wires leading from the switch to the connector and didn't find any signs of broken wiring and so I took my test light and stuck it into the connector and only got a faint glow not a bright light. Next I took the fan motor assembly out and hooked a set of connectors up and hooked it to the battery in my wife's car...and the fan motor ran just fine. so I hooked it up in my car again just to see, but still no go... Is there a resistor or something in the line that may be burnt out and not letting enough voltage reach the motor to run it?
I have bought an new blower but don't want to try it if there may be another reason why my original won't run.
any help would be appreciated since it's pretty cold outside these days.
