Blew brake light fuse and then the cruise control won't shut off

[Rich and Cork]

Last week I had a wire in my 7 prong connector come loose from its connection, caused a short and blew the brake light fuse. The problem is that I was using my cruise control and when I hit the brakes, the cruise control would not turn off It would turn off using the smart wheel on/off button, so it was not a giant problem, thank goodness. In addition, the Pac Brake would not go on, so it uses the voltage from that circuit also.

The problem was in the 7 prong connector to my tow car. In this case it was the ground wire. Some years ago when I made the connections, I obviously did not tighten enough.

Just thought I would post in case someone else had this happen.

Rich,

Where is the brake light fuse located?

Thanks,

On the 2003's, I know that there isn't a traditional fuse. It is a breaker that if tripped, will automatically reset after a few seconds. Not sure on the 01s.

Most vehicle cruise controls sense the brake light filament resistance to ground and will not turn on if both bulbs are burned out. When the brake is applied 12V is applied to this lead and the cruise turns off. In your case the blown brake light fuse prevented 12V from being applied to the cruise control which would not turn it off.

It is behind the panel in front of the passenger seat. It is a 15 amp fuse in my case and is clearly marked.
