I have noticed that the fan on the right side of my dash squeaks when the heater or A/C is on the lowest or second to the lowest setting. I am hoping all it needs is some lubrication. Does anyone know anything about this?

Thanks!

 

Idea #1) A cracked A/C housing.
The blower motor is mounted to a plastic duct or housing. There may be a small crack in that housing which squeaks under certain conditions. Test for this possibility by running the blower and when the squeak is heard, use your hand or foot to press gently on the blower motor. If the sound immediately vanishes that is a sign of a crack. The remedy is to find the crack and goop it up real well with a sealer of some kind. Products such as silicon rubber RTV or Welder or Shoe Goo would do the job.

Idea #2) The blower motor needs lubrication.
Remove the blower motor so you can bench test it. Use a pair of fused test leads to supply 12 volts directly from the battery. If the blower motor shrieks, it probably has dry bearings. Being a thrifty sort, I would always try to rehabilitate the old motor rather than install a replacement. Blower motors typically don't have ball bearings; the armature shaft spins in sintered bronze bearings. You may be able to lubricate them and give that blower motor a new lease on life. Use a light lubricant such as 3-in-1 electric motor oil.

 

is it the same problem when you hear a clicking noise from the fan? mine makes a clicking noise when i have it on the first two low settings.

it would be covered under warranty for me, i just have to get time to drop the car off..

 

A clicking sound may arise from a leaf fragment, a bit of paper, a piece of cellophane finding its way into the heater duct. This will make a clicking sound when it rubs on the blower cage. It is similar in principle to the child's trick of clipping a playing card to the fork of his bicycle in a position to click against the spokes as the wheel turns.
