2001 impala blower motor problem

[sassygramma]

hey ya'll

i am inquiring about a new recent problem where the blower motor on my oh so wonderful piece of crap '01 impala which now has 65000 miles , is kicking on even when car is not running and no key in ignition .

bout week ago noticed it first time when as soon as i put key in igniton it came on before car was even started , and the switch was turned off . this went on for about 10 minutes before it finally shut itself off , and i had then lost temp control 1 , but still had 2 , 3 , 4 , 5 .

now yestrday it also seem to change temp speeds without touching the control switch to where eventually it seemed to be stuck on temp speed 5 , and stays on when switch is agin shut off and car turned off .

i now have to pull the HVAC blo fuse , becasue it seems to be draining battery .

this forum has helped me to determine some of my last problems with this car and am hoping it will help again . i can not afford a new car right now so that means sticking more money into this one . but if you all can help , then i save some by not having to go to dealer again , they charge $125 just to pull into their garage . i am still basically right on schedule , for having problems at bout every 11,000 miles .

In addition to the HVAC [1-5] fan control dash switch, there's a relay that applies full power for the higher fan speeds -- the relay may be stuck closed such that the variable control can no longer turn the blower off.

The blower motor speed control resistor pack may also be shorted out -- The blower motor, resistor module, and relay are all located under and behind the glovebox -- to get to them, you need to drop the blower motor -- it's really easy, 3 screws -- you can probably replace the module and relay yourself. Since you can't tell if they're bad by just looking at them (unless they look like they've been under water) -- you may just have to buy the parts and save the labor for yourself.

The problem may also be in the fan speed switch itself -- some WD-40 to the contacts under the speed control knob has fixed this for some.

tyvm SpinnerCee for the info . at least i now have something to go on . this forum is the greatest help to me , considering i really only know how to put gas in , check oil and drive the dang thing ; and it sucks going in to mechanics casue being female they really do treat me like crap sometime .

If you have any other electrical gremlins, like the information center dimming/going out, interior light issues, etc... you may need an ignition switch/harness assembly. This switch is a known issue, the contacts start arching and will cause your symptoms.

NO other known , electrical or otherwise, issues related to this problem . one thing tho ...even with the HVAC blo fuse pulled , if control speed switch is turned on the blower still runs at speeds 2 - 4 ?? how the heck can this thing still be blowing and running with no fuse ?? but as long as switch is off and fuse pulled , it stays off ...

hey.... just replaced the resistor ($30) and so far everything seems to be working normal again ...if this impala can even be considered normal
tyvm e1 for help

See, it was easy right.

I'm wondering if anyone has a price for the blower motor itself?

[sassygramma]

spinnercee .... price we got for the blower motor itself for the "01 impala was bout $90 at autozone , only thing is most parts for this car have to be ordered special , never have anything in stock around here , or have to get right from dealer and more than likely price will be much higher

An Update -- I had the water leak on the passenger side that first killed the blower resistor (so the fan/blower would only work on the highest setting), then eventually drowned and shorted the blower motor itself:

At the dealer, for the 2001 Chevrolet Impala [Dec2007]:
Blower Motor Assy. [part #52487083] $177.72
Resistor [part #89019101] $49.50

The part #'s are also the same for the 2001 Lumina and Monte Carlo.
