Noisy AC fan

All,

I've got a 96 SC2 that has developed a problem with the blower fan
when running on recirculated. After a while, it starts to make a
buzzing noise and seems to slow down. If I turn it off for a few
minutes, it seems to work ok for a while. Am I looking at replacing
my blower motor? If so, does anyone have any info on the removal /
replacement procedure.

Thanks,
Rob

 

Am I looking at replacing my blower motor?

It could be the motor, but another place is the blower speed selector
switch.

Does wiggling the switch help any?

Tim.

 

Didn't seem to but switching to outside air vs recirculated seemed to
quiet the noise.

 

I once had a dried leaf get suicked into my blower and that's a
mechanical sounding buzzing noise.

The blower's right under the dash on the passenger side, and comes out
easy. I think it's 3 8mm bolts and you gotta unplug the wire too. I
remember pulling it long ago to clean/check it, and I remember it not
taking very long to get out or replace. Check that it's ok, first. I
guess you can just run it on 12 car battery for a few minutes and see if
it acts up?
