so I turned my heat on in defrost mode this morning and i was driving and all of a sudden it started squealing like a pig. it stopped after about 5 seconds but then when i switched from 2 to 1, 1 to 2, etc. it sounded like there was a bird trapped in my glovebox going tweet tweet. eventually it stopped making noises. so what could be the problem?

 

did you check for birds? i think i remember a thread where they said it could be your belts in the cold weather when it makes that high pitched squeeling sound. bring a cat to chase the birds away in case its not the belts.

no haven't checked for birds yet... i'm thinking bad bearings in the heater fan motor

 

Once it annoys you enough - you need to change the fan motor.

Consider waitiing until the coldest day and you NEED the fan to clear the windshield. Beat the dash with your hand and howl.

 

warranty item perhaps? or should i just go ahead and do it myself

 

sure its not just oldies coming out of your radio?

"all the little robins on Jay bird steet...."


j/k

actually, my dads starting making that sound in his dodge.... took apart some stuff and found a dead RAT... (but, what was odd, it never stunk)

 

If the car is still under warranty, definitely let the dealer fix it. That's probably a real pain in the *** job.

 

if not under warrenty and you have plenty of time - i would remove it and wd-40 the bearings and see if that stops the chirping. You won't be able to replace the bearings - but you could grease 'em real good and see how long that lasts.

 

it hasn't done it since that first time. maybe it was doing it because it hadn't been used in a long time.
