Brake Problems

Kurt04 · May 14, 2008

When I wired up my trailer brake controller I noticed that the brake light on my dash was on, my tail lights were on, and my cruise control would not work. The controller worked right though. I unhooked the wire from the brake switch to the controller and tried other wires on the brake switch but none worked right. Now the wire to the brake is unhooked but the dash light is still comes on and stays on once I hit 35mph and the cruise still doesn't work.

I wired it up just as the instructions said, I don't know what could be causing this. Any ideas?

I completly unhooked the brake controller. Dash light was still on and cruise didn't work. I thought there might be a problem with the ABS so I braked pretty hard and the tires locked up, but the dash light went out. Then I tested it again and the ABS worked. Still no cruise though.

Anyone?

Did you bump or disrupt any vaccum lines?

I know I have a much older truck than you, but I noticed the Brake-Stop switch,

at least one of them under my dash at the pedal has that cruise vac line attached.....

Just wondering if your wiring was similarly located, but just a thot....

If it got partially bumped off it wouldn't draw vaccuum and work...just like hitting brakes

would release it....

readjust the brake light switch.

I don't see any vac lines under the dash.

readjust the brake light switch.

I have played with it, but no luck. A week ago I drove 2 hours non-stop and the light never came on but the cruise didn't work either. This morning the light flashed the entire 15min drive to work. Now it is back to coming on as soon as I hit 35 and staying on....
