HVAC blower fan works, dont work, works, dont work
In my 95 Caprice Classic my blower fan for my HVAC works when it wants to. Somebody told me about some kind or thermal resister that might be the problem. What do you think? How can I check my system.

Re: HVAC blower fan works, dont work, works, dont work
Next time it is off when it should be on--kick it, or tap on it--if it starts running, you need a new blower motor--the brushes wear- and stop on a "dead spot" and by you disturbing it-- it starts running- proves it is worn out.....
Of course you need to know if the connections are okay- try wiggling those if above test is negative.....
