My 78 TA, has a annoying creaking noise on the passenger side, around the ac vent, glove box area, whenever i hit a bump.
I pulled out the glove box, & ac duct assembly, & the kick panel fresh air vacuum solenoid, noise was still there.
Then removed inner fender, & blower motor, road tested it, & it was gone, a couple screws had backed out on the blower motor housing, so I figured that was the problem.
New GM blower motor installed &
Put it all back together, road tested, but the annoying noise is still there.
Anybody else had this problem?
