Brake light and rear turn signal problem?

[aretevince]

My problem is that when I press the brake my turn signal lights come on as well. Therefore when I put on a turn signal it flashes but as soon as I press the brake to stop my turn signal stops flashing and as soon as i let go of the brake its start flashing again. It is not a real big problem it's just really annoying. Can anybody help me out its just i don't know where to start looking when I have an electric problem. Thanks.

first place to start is make sure you have all correct bulbs and fuzes. then you start chasing wires

Thanks I will check that tonight but I didn't know that a wrong fuse or bulb would make a difference.

This should be an easy fix since all years of all models of all brands are wired exactly the same.
Seriously, you might get better responses from those of us bad memeory types
if you include the info on which truck with the question.

Ya sorry I didn't realize that I didn't put my truck info. Its a B4000 1994 2WD but know I have a new problem. Yesterday I was driving back home from my baseball game at around 10h30pm and suddenly the lights in my dash went off so I stop on the side to see what else wasn't working and I saw that my rear light (brake light) didn't work anymore but my head light did. Weird thing is that the problem I had in the first place disappeared. The problem I had in the first place was that when I pressed the brake the flasher lights came on and when I put on my turn signal and then pressed the brakes my turn signal would stop flashing. Know that problem disappeared because my turn are the only thing that work in the rear. I didn't check the bulbs or fuses yet but I hope I will find the problem easily because I wouldn't want to start looking through the whole electric system. Has anybody have this problem before?? Can anybody get me the electric diagram?? Thank you.

With my B2200, I have traced the problem with my tail lights to the switch. I dont know if the switch on the 4000 is the same as the 2200's. But you might want to start there, and work back.

Ok thanks I'll start by checking there after the fuses and bulb.

[aretevince]

Ok I found the fuse that was blowned I replaced it with a new one and my rear lights worked again but as soon as pulled the light switch it blow off again. I think there is a short circuit or something in my rear lights. Maybe my sockets. Anyways I'll check that tonight.

sounds like what everyone is saying bad switch will blow a fuse everytime

I looked at my problem more closely during my break and you are probably right about the switch. Thanks for everything and I'll tell you if you were right.
