Wiring issue please help

My tail lights are not working. The brake lights do work as well as the blinkers but the are diem. when i hit the brakes and the blinkers the rear finder lights come on and blink also. I put a new switch in it and i disconnected both tail lights and the fender lights still only come on with a blinker or brake light.

Thanks for any help.....

Check your grounds, make sure they are good, tight and clean.

And a make, model and year would be most beneficial.

yep check your grounds on the chassis sounds like your back feeding .....

I agree with Husk and LilJ. Everytime I have a wiring problem it ends up being a ground problem.

Thanks guys I am going to start with the grounds tomorrow morning. .... BTW it is a 93 chevy 3500

90% of the ones we see are grounds, and I see a lot.
