Greetings. I have been attempting to fix my truck now for a few days to no avail. I am hoping maybe someone has encountered these same issues and can point me in the right direction.

First off.... My truck is a 2004 F150 XLT, 4.6L 2 wheel drive extended cab

The truck starts fine. With no lights on, heater/ac blower turned off... my turn signals and hazards work as they should.

If I turn on my headlights, I have no turn signals and the indicators on the dash are slightly lit up along with my highbeam indicators. The actual dash lights do not come on.

The blower does not work at all regardless of whether the lights are on or off. Turning the blower on immediately creates the same issue as the lights. (no turn signals, slightly lit up indicators, etc). The blower does not work on any speed. I can hear the duct work changing direction behind the dash as I move the blower selector from dash to windshield to floor, etc. I can also hear the compressor kicking on for the AC.

What I have done: I have checked all the fuses. I have attempted to remove every one of them while running to see if anything shutting off would let the blower kick on. I have unplugged the blower entirely wondering if there was a dead short. I have removed and unplugged the resistor to see if that might be an issue. I have also removed the right side kick panel and checked the ground wire there that runs to the dash. Everything so far seems to be in good order.

I'm baffled here. I can't help but feel there is a dead short somewhere in the system. I just can not seem to find it! Any help is appreciated.

 

You have a bad ground somewhere. Start at the battery.
There is a ground from the engine to the frame, and a couple o the back of the motor to the firewall.Check them all.

 

This is a duplicate (multi) post.

He's already been told exactly what to check in his other thread.

 

Hmm, I thought the issue looked familiar.
