Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hi Eric, since our last discussion, my 2002 Buick has been driven on 11 outings. The air handling system has worked twice. There seems to be no rhyme or reason for why it worked on 2 occassions and failed on all the rest.
You're the pro and I appreciate your help, but what do you think about this issue with this new information, please. Don't ya just love intermittent problems..??? Aaarrgh!
Hi Eric, Now the score is 3 out of 15. Yup. It's been driven 4 more times and worked once.
Where the heck is the wiring harness and blower motor? I made a quick inspection. The engine compartment and firewall are not like my 71 Chevy...
I stopped at the auto parts store and they had a blower motor that I could get - which I did and return if that's not the problem.
1. I removed the trim panel per instructions.
2. Slithered into the foot well - oh my aching back.
3. Turned ingnition to on and the blower spun. (4 out of 16)
4. Wiggled and jiggled the wires (thin brown, purple w white stripe, black) and the fan would sputter.
5. Seperated the wire harness. Tough to do.
6. Re inserted the wire harnes.
Now get this.
7 Wiggled and jiggled the wires (a LOT!) and can't get the fan to sputter. It just keeps spinning.
We last visited as Christmas approached. Now Thanksgiving is here. I hope you are looking forward to the Holiday.
About the fan in my 2002 Buick, since we talked I have put up with the intermittent performance of the fan for 11 months. It would have its spells of being ornery and not spinning, but for the most part it behaved at a performance level that was tolerable.
Then it stopped and would not restart.
I extracted the fan motor from the dash assembly. While trying to test the fan I was handling, turning, and tipping the fan motor assembly. There was a fine black powder that kept coming out of the assembly. Hmmm?
What was/is the powder?
Does that point to or confirm the cause?
Finally the amout of black powder that would fall out diminished. I reinstalled the fan. It both works and fails. But, I think it works slightly more dependably.
What is your conclusion, please, Eric?
What needs fixed?
Outstanding, Eric!! A replacement unit from auto-parts retailers has been quoted at $240 - $280.
I was slow to pull that trigger without some confirmation.
What about... used parts?
What about... Thanksgiving?
At O'Reilly's their rep brought out those 2 assemblies. I had my blower motor and mine looks different from those 2.
At Advanced Auto, their rep found 3 fans on their system. The same 2 just discussed, plus one that...
- looked like mine,
- looked like the diagram you sent on Tuesday, December 13, 2011 3:44 PM EST, and
- was way more expensive (Advanced Auto = $240. NAPA = $280).
What do you think, my friend?
I'm not sure about which replacement blower motor to buy. But, but, but that is not your issue. I'll work through it and get the right one.
You provided the terrific answer that the blower motor was the culprit. Thank you, XXXXX XXXXX thank you, Eric.
