2000 chevy blazer automatic. reverse lights staying on????

bad switch

there's a black box under neath the steering wheel behind the panel unplug it it worked for my blazer i had the same problem it took me 2 months to figure it out i changed all the dome light switched and the fuses so i unplugged the black box under the dash below the steering wheel and it works fine now

I have a 1995 Chevy 1500 4.3 v6 trans bands need to be adjusted I have two out of the four gears. Reverse tends to slip but works. How do I adjust the bands. And what side are they on. I baught it as is.

Either you have a transmission rod off or out of adjustment or a bad reverse gear in the transmission.

Sounds like a likely possibility, the reverse method definetly did the trick in loosening the brake, but it may still be slightly applied, put it in a warm place when you can, or have a shop look at it indoors, it may need to be re-adjusted, or even just warmed up until the cable frees up again

sounds like reverse let go you need to have trany rebuilt. soory for the bad news, good luck.

chk trans fluid level running and in park.

you need to disconnect your headlight switch if they go out your switch is faulty, if they stay on you will have a headlight relay fitted somewhere, look in handbook, disconnect relay if they go out relay is faulty. hope this helps.

Did you check the level of the coolant? do it while it is running............but make sure it is cooled off.

take the pos cable off leave it off for a bit and see if it wont reset
