So my 2003 GT Auto wouldn't shift out of park today. Hmm, been down this one with other cars and it's usually the switch next to the brake pedal that gets actuated when you press down on the pedal. Some cars have 2 switches, one for the brake lights and another to activate the solenoid that allows the shift lever to move out of park.
My suspician is that the switch either loosened up or fell apart.
I've seen both on various cars.
VW Jetta/Golf are famous for this one.
Anyway, I crawl under the dash and try to press on the switch and Bazzzzammm the snap of a few sparks, a quick whiff of ozone (guess what movie that's from) and I say to myself " I think I found the problem"..
To make a long story short, (haha get it?) the way Ford routed these wires, at least in my car, will most definitely result in them chaffing and ultimately shorting out.
Both wires were showing exposed wire where the insulation was worn away.
The fix is to cut the plug out, splice in new wires using a soldering iron, putting heat shrink tubing on them and then wrapping with electrical tape.
Oh yea, route them away from any metal like the brake pedal arm
And make sure to disconnect the battery as well while working on it.
The reason I post this is that if my car did this, chances are some other folks have a time bomb waiting to explode. I would suggest crawling under there with a flashlight and doing a preemptive strike looking for chaffed wires before they fail.
Good luck !
