I have a loud hum/scraping noise coming from my blower when the climate control is on. What am I in for? Does the blower go bad? How hard is it to replace?
I've had to replace my blower a few years ago. Made noises just like you describe. If I sped up the fan the the scraping noise would speed up, like a once-per-revolution sound. I bought a replacement fan from Rock Auto. It took about 30-40 minutes to change as I had to contort myself to get face up under the glove compartment to remove the three screws that held it in. I can't remember the cost for the motor. It was less than $100.I have a loud hum/scraping noise coming from my blower when the climate control is on. What am I in for? Does the blower go bad?

This is 100% what I'm hoping. And my next step.have you checked the cabin air filter? maybe it has degraded/torn and part was sucked into the fan.
I've never seen evidence of moisture in the cabin or in the dash when I changed the cabin filter last but I'll keep my eyes open for that. Thanks.We had a very noisy fan, replaced it with an aftermarket fan found on Rockauto. I found the bearing to be in bad shape, water would get into the cabin because the windshield drains were blocked. Remove the corner of the wiper cowl (plastic panel, the ends use push pins) and clean the drain so the water does not get into the cabin by leaking on the blower, causing the bearing to seize.
