Just bought a 2004 f150 lariat and it has a wierd issue. When I turn on the left turn signal, the rear tail light hyperflashes, but the mirror, front, and dash left turn signal do not flash. I replaced the flasher and it fixed the hyper flash, but the front left light, mirror, and dash still don't light. PLEASE HELP!!

 

Did you check the fuse or fuses

 

I have not checked the fuses because I figured if they are working on the hazads the fuses should be fine. Also, if it was a fuse for the left side, why does the back still work? I will check them tomorrow.

 

Don't have a manual. Does anyone know which fuses I should be checking or have a schematic of the fuse box?

 

Send me a P/M with your email address and I will send you an owners manual and maintenance guide.

 

We checked all of the fuses in the fuse block. There was one fuse blown which we replaced but it was for trailer lights, but had no effect.

 

have you verified the bulbs are good ?

 

Yes, all the bulbs work when the hazards are on

 

I'm thinking of replacing the switch to see if that fixes the issue.
