Heater fan or blower pressure.

Asked by heavyhauler Nov 04, 2008 at 02:20 PM about the 1994 Oldsmobile Cutlass Supreme 4 Dr S Sedan

Question type: Maintenance & Repair

I bought this car last year and inside fan seemed to blow quite well, with good
force on the high setting, now that the car has been parked for a few months it
seems to blow really week. The fan speed settings work normally and the sound that
it makes is the same as before but not the pressure, could it be a clogged vent
pipe? Or is there a filter for the inside air? Where does the air get sucked in
from?

Alright bud, the air actually comes from the vent thats between the hood and the windshield. so if there is leaves all over that, then that could be an issue. I would also check the connection on the blower motor itself. if it was a clogged vent pipe, you would notice that some heat options would still be strong but some weak. The first thing i would do is to clean the connections on the motor, if that does not work change the motor, if thats not it, take the motor back and claim defective to get your money back, and if thats not it there is something between the blower and vents blocking it. which means you may have to tear apart your dash.... ugh.
