I have a 1990 c1500, 350(5.7)
Fleetside 2WD silverado.
The lights switch is not working right. When I push it down(turns lights on) only the headlights turn on. Break lights, cluster, and parking lights dont turn on. I turn the signal light stick down to the left, and the signal lights work. Both left and right but after I turn the signal lights off they stay off. When I press on the break the lights come on, other then that they stay off. Do I need a new light switch?

 

I believe that it would be a fuse, all of the non working lights are on one fuse.

 

I checked all the fues's and they are all in working shape. That's why I'm at this point. outside help, opinions.
