Question about 1999 Chevrolet Blazer

2 Answers

All 4 power windows on 1999 Chevy S-10 Blazer started moving slow and then stopped working.

1999 Chevy S-10 Blazer. All 4 windows were working fine, then they got real slow, and now they won't work at all. When they started getting slow it was like when a motor is going out. But they all 4 done this at the same time. The motors are not bad because a couple of times they started working again. One time they went down and right back up like nothing was wrong. Then the other time the front passenger door was open and they went down and up. Never heard of all 4 windows doing this at the same time. Any help would be greatly appreciated. Thanks for any help.

    Well no luck with the switches. I think I have a ground problem. I can open one door and nothing happens. If I open the drivers door and one other door everything works fine. Another problem when the doors are closed is the power mirrors don't work. Now I have a new problem to go along with the other two. The reverse lights stay on all the time now. This just started 10/02/08. Is there any grounding straps or wires that may be loose on the doors? Thanks for any help.

Hey there Bubba,

Had the the same thing happen to me on that Blazer in my picture. All of them going at once is the key symptom here. What do all the windows have in common?

Check the the window functions from each door/window switch. Any difference in performance from the drivers controls?

The switch itself is usually the problem . Over time the contacts get scarred, worn and unable to transfer current. The drivers controls are used more often, as such are usually the first to develop symptoms.

I'd check out a local wrecking yard for an inexpensive replacement.

Let me know how it goes
Mike

    One more thing,

    When looking for a replacement switch, it can be useful to have the old one with you to match the Pin/Plug pattern. There's quite a few variations.

    Good luck Bubba,

    Mike

Where the speed control at on a 1999 chevy blazer


Most of them I've seen are a sensor attached to the transmission. Tipoff is that it stalls when moving over 10 mph. Sometimes it can become dislodged, over times a poor connection due to crud buildup.

94 chevy s10 blazer power windows not working


I had the same problem - driver side fine, passenger side front not working/slow or the back seat. You need to replace the window motor on the passenger side. Yes, there are two motors. It's pretty simple if you are handy with some tools. The hardest part is getting the 4 mounts that hold the window motor to the door off. The are factory riveted to the door, so I had to grind the outsides off and tap them out. Just watch the spring lever that holds the window bar for going up and down. I didn't pay attention and it snapped back - nearly broke my thumb.
