door locks activate when push on brakes

[MinnesotaMike]

I have a 2002 F250 7.3 diesel that is acting strange.

The door locks activate when I reach a certain speed ( normal ) when I push on the brakes they activate again and again as I get to a lower speed, say 20 mph. Truck runs normal otherwise it is just annoying to have the door locks clicking.

It sounds like there is a activation switch that is shorting when I hit the brakes causing the locks to activate, how could I possibly find the problem?

Thx,

Mike

Harness short or activating switch going out!

Not always the case but often, weird stuff happening = bad ground(s).
