crickets, squeaking noise

Post by Tommys 89 635 »

Went to get some gas this past weekend and it was pretty warm in the bay area so I turned on my fan speed to low and i hear crickets and turn up the speed a little bit more and hear squeaking noises, I hear the same when I turn on the AC. Is it the blower motor? Can it be oiled/lubed? or should I get a new one? thanks

Pretty odd that you hear it with either fan on. The AC fan and heater/defroster fan are separate units.

Try to isolate which motor the noise is coming from. The A/C blower is inside the dash, while the fresh air/heater blower is just forward of the cowl and is much easier to change. Mine (fresh air blower) was making the same irritating squeaking noise; cleaning and lubing the bearings didn't help so I have a new one on order (~$320.00).
