So This morning I woke up started up the car for work, and sat for a minute to let it warm up... Then I realized the window wasnt defogging..... SO I reached down to turn up the fan, which was on medium (3) but no air was blowing, so I turned it up to 4...still nothing, so I went back down to 2 and 1 and still nothing, so I cranked it and the lights dimmed radio dimmed and engine seemed to almost die!!! But voltage went back up and ran fine once switched to high. So survey says??? Blower Motor resistor? Blower motor itself? Both? I am almost at 110k and I think its starting....

If it only works on max, its the resistor

So I tried searching, is there an article or thread on replacing the resistor? I am sure someone has done it before, is it a DIYer or a shop repair?

Fair warning, replacing the BMR is in theory a simple process, but in practice it sucks. I had to pull the seat out of the Monte to get enough room to work comfortably. Another tip, don't remove the screws entirely. Look at the new resistor and see which way you have to move it to get it to slide out without removing all the screws.

I am a big guy so I may end up removing seat.... Is that hard to do?

As long as you aren't dealing with a a seat that has an airbag it's a cakewalk. On the Monte is was as simple as pulling the seat forward, removing two bolts and then pulling the seat off the rails.

The best way I have found to work up underneath the dash (even on the drivers seat) is to push the seat all the way back, tilt it back at a 45 degree angle, and get on the seat upside-down. Your head and arms are basically above the floor, your lower back is on the seat bottom, and your legs can go up over the back of the seat and your lower legs can hang off on either side of the headrest.

Or, just push the seat back all the way and open the door and kneel on the ground and lean over the whole time. Smile The BMR is a PITA because there isn't enough clearance to get in there with the carpeting and insulation and get the screws in and out. Fortunately I have only had to do mine once after losing speeds 1 and 2 on my fan.

Hmmm.... Maybe I will just hire one of my smaller buddies to do the hard part lol. I have one that owes me some favors lol. That or start a stretching regimen before I undertake this task. lol

FWIW, after I did mine once, I told myself if it ever needed to be done again that I would pay a shop to do it. It isn't worth the frustration of doing it yourself. Alternatively, you suggestion to recruit a small friend is very good. Just make sure you have beer for him when he is done.

When I worked for a shop, we charged .6 of a hour which came out to $51 plus tax. Mechanics hated it and thought we shoulda charged more. Might me worth it to take it to a shop and have it done.
