Here's the problem low beams work perfect, high beams only work on flash mode. I have taken apart the column and cleaned out the combo switch. I switch on brights, the light on the dash lights up, but the headlights die. I've been trying hard to fix this problem but cannot figure this one out.

 

Helps to know what kind of truck you have ?, have you checked the headlight relay ?, they can go bad and cause the problem your having.

 

89 4runner 22re. Where is the relay located?
