Maybe your blower resistor

Checked resistor and it looked ok. Checked power to blower fan and good power, good ground. Pulled out blower fan. I turned it on and gave it a spin with my hand and it worked. After a bit of off on off on it wouild not spin. Figure a dead spot on commutator. Only 500,000 kms on it lol. Made a 1/2" hole in motor housing opposite of cooling hole for motor. Now can spin it a bit with eraser on pencil if it wont start spinning. So now heat for Mon early morning hunt and get motor at wreckers...

Maybe your blower resistor

that controls fan speed. normally when it fails you only have high speed.
