Engine/Transmission (1994 - 1998) ABS and brake light

[snake]

Have a 1996 3/4 ton diesel, ABS and brake light, stay on all the time. Any idea why? Thanks, David

Sounds like your clockspring is broken.

There are several things that cause both lights to illuminate. Could be something as simple as the ABS sensor in the pumpkin, could be a lot of wire chasing and a teaspoon of water in a connector. Search is your friend, a good factory service manual is a must have. I prefer the paper manual when chasing wires.

I blew the brake line that runs to the back axle on top of the gas tank. Ever since my brake light stays on. If I disconnect the batteries the brake light will go out, but when I start the truck, it will slowly come back on. Starts out dim and gets brighter.

Anyone run into this issue?

My problem was one of two things I fixed:
Abs sensor on top of rear axle, or a small vacuum leak in the cruise control line. *Fixing those two things seems to have fixed my lights coming on.

It could have been either one. '96s and earlier have a vacuum pressure switch in the ABS system.
