I have replaced the blinker switch and relay and fuses and still have no headlights or blinkers and brake lights do not work.

Hello,

Can you check for power at the fuses 10 and 2 ? Here is a guide and the headlight and blinker wiring diagrams so you can see how it works along with the fuse locations.

We are losing power somewhere please run some tests and get back to me.

Cheers, Ken

I fell asleep at the computer last night after grabbing a few diagrams from Alldata. Took me a while to find your question again!

Maybe they might aid with what Ken posted for you.

The fuse numbers may be more legible.
