woblik Posted October 21, 2010 Report Share Posted October 21, 2010 Well, HVAC blower hasn't worked for a month or so. Hadn't been a problem until our first frost this morning. Dug into the dash, found the blower's resistor housing and plug melted. $130 later, fan is working EXCEPT in high speed. It'll work 1-4 just fine (pulling 0.3 amps FYI) but when I put it to 5, the resistor housing clicks and nothing happens. Is the blower bad? I don't wanna burn up another resistor thing, well, i more so dont want to shell out another $130. Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted October 21, 2010 Report Share Posted October 21, 2010 There is a chance that the blower motor is bad, but there is also the chance the the new resistor is bad also. I believe that there is a high speed relay built into the resistor that bypasses the resistor itself so that the blower motor can operate at 100%. Sounds to me like the new resistor is NFG, I would take it back and ask for a replacement. If you install the new and the same thing happens, then it is time too look beyond the resistor..... Did you buy AC Delco parts? Quote Link to comment Share on other sites More sharing options...
woblik Posted October 21, 2010 Author Report Share Posted October 21, 2010 Ok, thats kinda what i thought. And no, i bought advance auto junk. I think its bmd brand or something Quote Link to comment Share on other sites More sharing options...

Blue2003SS Posted October 21, 2010 Report Share Posted October 21, 2010 Where is the resistor located in the dash? I just lost the setting #5 on the fan this week and fear the resistor and the fan are crapping out. Quote Link to comment Share on other sites More sharing options...
woblik Posted October 21, 2010 Author Report Share Posted October 21, 2010 Under the glove box, take off the black plastic cover (3 bolts). Then youll see on the right two screws holding the resistor assemvly in place. It has a plug and two wire going to the blower Quote Link to comment Share on other sites More sharing options...
