If the blower motor is noisy, the bearing may be getting bad inside the blower. This will require replacement of the blower motor unit. In some cases, foreign objects can fall into the motor casing assembly also making a noise. The motor will need to be removed for inspection
Sounds like a seized up (bad bearings) blower motor. It may not pull enough current to blow the fuse at the lower fan settings but does at the high one. Something could also be jamming the blower fan in its air duct.
Most blower motors can be accessed under the hood. Replace the fuse then put the blower switch on one of the lower settings (don't blow the fuse). Get yourself a good sized screwdriver and hit the back of the blower motor with the screwdriver handle a couple of times.
Sometimes (unless the blower motor has totally seized up) you can get it to spin and this will tell you for sure you need a new blower. Other than that, you can get a spare blower motor, remove the connection wires from the old motor and hook them up to the new one to test before you go to the trouble of replacing the blower.
I had same problem.I would turn temp adjust switch and I would here this loud clicking from in the dash ( sounded like a plastic gear was stripped) and then it would go from a/c to heat or vice versa. I limped it along for a couple years, finally wouldn't change over to heat this year. There is a motor that controls a heating valve that failed. I could only get it the motor from the dealer. Had a guy that specializes in a/c work install it.
I think your talking about the heater fan? If you hear more noise as you increase the blower speed, there is something in the squirl cage or a problem with the blower motor itself. Leaves, paper or something lite on the pass side floor, it will get sucked into the recirculation duct,causing a noise.Remove the blower motor and clean out any debris, and inspect the squirl cage and turn the motor by hand to see if you hear any noise
ok well its possible there may be something stuck in the blower motor under the passenger side dash. ..or the blower motor itself could be on its way out, sometimes leaves or sticks from trees and even stove inside the glove box can find their way into the windshield cowling and into your blower motor..u can remove it to check by unplugging its white connector and remove the 8mm bolts that secure it into the heater core box..its very easy to remove..the 8mm bolts / screws should also have a phillips head on them...
