My front 12 volt power supply quit working the other day, but the cig lighter and rear 12 volt are still working. Do I have to take the dash apart or is there another way to fix them?

 

It has its own fuse that is separate from the cig lighter and rear power point. Its a 20A fuse #39. I bet that's your problem.

 

Just had that fixed it's the fuse I was getting my oil changed today and they fixed in in like 2 min! Haha it was really easy!

 

Thanks, My other fuse was blown so I just figured it was all one the same system.

 

Good deal, gotta love an easy fix

 

My lighter and front power point are dead. I replaced the fuses and still have nothing.

Any thoughts?

 

Is anything else dead? Have you (or anyone else) messed with the wiring in any way (added any aftermarket stuff?) I'm pretty sure the cig. lighter fuse also powers the OBDII port under the dash. That and the power point should both be 20A fuses. Are those the mini fuses that you replaced? Take a test light (or DVM) and see if you have juice coming to the fuses. Should be 39 & 41.

 

According to the manual its fuses 110 and 117 and they're cartridge fuses. Theres power in the fusebox but none getting to the ports. There is a line level converter in the dash. I'll have to pull it apart and have a closer look.

 

Hey you were righ about the fuse locations. My truck is an 07 and I downloaded the 07 owners manual that gave those locations. Must be some mid-year change up.

Thanks!

 

I have an F150 2006 flareside and My dash 12 volt was inop, so I pulled the #39 20 amp and yes it was blown at first I thouhgt 8it was ok till I put a light on it then I could see a 1/16th gap, any ways i replaced it and its working fine.
