headlights dont illuminate....
for some reason when i turn my headlights "on" the tail-lights come on but the headlights dont, i have tried the high beams aswell, checked the fuses, and the one's in the engine bay but NOTHING has changed!...
this has happened one time before, the headlights went off for a few mins then back on and i never thought anything of it, but now they wont come back on after almost two days!...
i have searched and nothing has helped me thus far, idea's!?..

Turn signals would be the fuse in the interior.
Headlights are fairly easy to figure out. Just remember that when you go to ON with the headlights, what your doing with the switch is putting a ground on the coil of the headlight relay. Power is already at that relays coil from the HEADLIGHT fuse in the engine bay.

Ignore my FIRST post on that thread. It was just dummy talk. I attached jpgs of the circuit and the relays location and HOW TO figure it out.
I forget right now where the turn signals get their power. I THINK it's the TURN fuse. Check out the diagrams if that isn't the problem.

Go to the CPU and find the two wires that come from the signal switch. Turn the signals on for left or right, your choice, then put a meter on the wire for that side. You should see voltage after the signal is selected.
Seems you could just pull the plug off the CPU and get on the Green/Red or the Green/Yellow wire with a meter, and when you select left or right you should get voltage on the respective wire. Key to ON first.
IF you dont' get any voltage, and the fuse is good, then you need to visit the B/R wire in the Cluster switch. It comes almost directly from the fuse box and should have batt voltage.
Also, do your HAZARDS work? It uses a different fuse than turn, but the same flasher is used and the same tail/front lights are used. Whether they work or not would be a large clue.
Also, when left or right signal is selected, do you hear the flasher in the CPU clicking and do you see the indicator lights on the instrument cluster blinking? Probably not, but????
FSM jpg of the CPU and the flasher board in it. Someone in the last week posted jpgs of the flasher unit board removed from the CPU.
