Brake light issues, Need help.

[doubleb's69]

To start off I am not any good at anything to do with wires or electronics but I try to learn. I noticed the other night that my brake lights are not working. I have tail light and turn signals but no brake lights. I eliminated the tail lights because I know that they run on a different circut. So now I am confused as to why I would have turn signals at the rear but no brake lights since they use the filament.

I used a test light to check the pressure switch and the pedal switch and each had power. The pedal switch had power in and out when depressed.

I turned on the four-way flashers and only the front worked. Eventually I wiggled some wires around under the dash and got everything to work including brake lights and then it quit again.

So does anyone have any suggestions for me. There are a couple of shows coming up that I would like to attend with my truck so brake lights a really important to be on the road.

Thank you in advance,
Bud.
