Whenever im driving my car for over like ten minutes, the lights start going on and off in like 3 second intervals. I just changed the alternator 2 weeks ago so idk what it could be. Any advice would be great . Thanks

 

It sounds like your headlight switch is bad.

 

Yea, that or maybe some loose wires

 

is it a gt or lx? and do you have foglights?

 

it is a gt and yes i do have fogs but they dont work, or not hooked up.

 

bump

 

What year is your car?

 

my cars an 88

 

It sounds like a short somewhere.Did you ever have this problem before you changed the alt? If not the problem lies in there.....Maybe a bad alt or switch....Good luck

 

Take out you turn signal switch and headlight switch and you will see the melted connectors. Change those switches and plugs and youll be good. Ive seen this a ton of times i worked at a ford dealer.
