Sorry if this is a simple fix/question that has been covered 1000 times but I searched and couldn't find any solid answer.

The truck is a 2002 Super Crew FX4 4.6L. I've been using the 4wd a lot over the last few days, due to the blizzard on the east coast, with no issues until today. My turn signals went out, the ABS bulb check didn't work and the 4wd wouldn't lock in the front end. I found a blown fuse, replaced it and that took care of all the issues... except the 4x4 light stays on (red) when in 2H. If I turn the *** to 4H it locks in the front and the indicator turns amber.

I'm assuming I have a stuck actuator or a bad relay... any thoughts?

Thanks!

 

Pulled the codes and it's a P1804... might just be a short to the light.
