Electrical problem V8 All Wheel Drive Automatic 100000 miles

every time I touch the brake the right turn signal comes on. If I use either the right or the left turn signal then both of them come on at the same time. I checked the fuses and the wiring. Do you know what it could be?

This could be anything from bad bulbs and it could be anywhere on the truck front or back. It could also be a bad ground. There are quite a fewon your turck but i'd go for one on the left side under the panel next to the dash. There is also a flasher module on the ip fuse panel which is also near where the ground is there. It could also be the ground on teh battery which if you disconnect the battery you will need to reset everything like clock/radio, etc. Other than that have pro look at it.

It sounds more like the socket or bulb has melted in the rear of the car on the left side. Can you please remove the lens and brake light bulb and check it out. Look inside of the bulb.

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken
