The last 3 or so days in a row when my fans have kicked on, they make a horrible noise for 20 or so seconds before returning to normal fan noise. Is there anything in there I can lube up or should I just buy new fan motors? I took a look up there already to see if there were any obstructions, there was not.

 

You should get ready to replace the motor on whichever one is squealing.

 

mine squeak after i shut the car down and the fans come to a stop.

figured it was time to change the motors.

where do you get them? dealership? would rather not go used.

 

Thanks shoebox. The motors are around 50 bucks a piece from advance autoparts website. GM part no. 12101917 ac delco p/n PT189, from shoebox's website

 

Are the motors the same as on an '03 Trailblazer? My wife's TB is having the same issue with the 20 second squealing.
