This TSB article is being republished in its entirety to correct the supersede article reference.

ISSUE:

Some vehicles may exhibit a "squeaking" or "chirping" from the blower motor at low blower motor speeds. This may be caused by uneven brush friction on the commutator surface of the motor.

ACTION:

Replace the blower motor with a revised blower motor which has improved brush-to-commutator friction. Refer to the appropriate model/year Service Manual for removal and installation procedures.
