air conditioner and heater fan doesn't come on unless I hit dash board
the heater/blower fan makes an awful noise when on higher fan settings. Can run on low but not so effective. can the heater/blower fan be repaired rather than replaced?
A/C fan doesn't always come on at start-up. Seems to start and run OK when vehicle crosses RR trax or just while driving. Where is the most likely open in the fan circuit?
my air condition is not working at all not even the heater. no cold or hot air coming out.no wind at all coming out of vents when air condition is on
Thought it was resister. Now i find that if i pull the plug from motor and plug it back in then it will operate. But after shutting off car i have to repeat my procedure. anybody got an idea
