#1

2001 chevy malibu, 115,000 miles, blower fan for ac is operating intermittently, blows full force sometimes or hardly at all other times, any advice for cause?



Bonus loaded question- cost of repair


#2

Poor connection at the blower motor? Its right under the glove box - you might have to pull a trim panel - but stick your head down there, pull the plug, inspect & clean.


#3

Are You The Original Owner ?
Has It Always Behaved This Way Or Is This Something New ?
Does It Have “Automatic Air Conditioning” (Blower Speed Has Automatic Position) ?

Bonus loaded question - Have you consulted your Owner’s Manual for proper A/C operation ?

could be something such a leaves got sucked into the ducting. Could be the AC door is flapping around loose. could be a poor connection in the wires.


#5

Im not the original owner, problem developed recently. The blower has positions of 1-5 settings, and have consulted the owners manual and checked the fuses.

Replaced many.many HVAC control heads over this, but I had the luxury of “stubbubg” in parts to test with. I never paid attention to the price the customer paid, just the amount of time I “flagged”.

I remembered something that happened with many GM HVAC control heads and the inability to change fan speed and it was pretty simple, the knobs would lose a grip on the speed change switch shaft, the fix, new knob, happened many times.
