Headlight/Signal problems

[domenad]

For some reason now, when I pull my headlights on, all of my headlights come on, including my brights, but weakly for some reason. Also, my right flasher light comes on and stays on. I replaced the flasher with an electronic one and at least I can use the flasher now, but the light still stays on all the time. I know the headlight switch can cause a problems, but replacing it did not help- same problem. Is there a headlight relay that might be bad perhaps? Where is it located if it is?

First thing to start checking is grounds. When the grounds on the wiring get iffy, goofy stuff starts happening.

I think your signal/high beam switch might be bad. Does doing anything with it affect whats going on??

same thing was happening with one of mine. it is a ground in a fender. mine was doing the same, i would get out and hit the fender by the headlight and it worked fine. my driver side headlight would flash when i had the left signal on. it was weird since it started on halloween. check for grounds since a wire might have come loose or corrosion has built on the wiring.

Nates car does exactly the same thing, right turn blinker indicator comes on, and the parking lights go out when the highs come on. headlight and MF switches have been replaced. Was thinking its a ground problem, will have to check the ground mentioned. Thanks.
