Hello there, new to the group but I'm having a problem with my truck and I'm stuck. About 9 months ago my 4wd stopped working.turn the switch and no light or noise. I took a look at fuses and everything was good there. I let it go but now I need 4wd. Today I checked every fuse and all of them were good. I moved to the relays checked them and they were good but for the heck of it replaced them. Checked for power at the pins. The one that needed power had power. Next I went to the switch had 12 volts there. Pulled switch and test with a multimeter and ohms were good. Went. Down to the motor and tested for power there not power to the motor. Is there anything else I'm missing?

 

I've never had to mess with the wiring before, but the way my brain works is, if you tested everything and it had power, but then you tested at the motor and you had no power, then I would back trace, follow the line back from the motor to the next point, if you have power at that point then then you're losing power, between the 2 points, maybe a broken wire? A connector/ connection?

 

Hey Tommy65i ... welcome aboard the FTE board. It helps if you tell us more about what truck you're driving. Lots of people put the details in their signature. Hopefully some of the more technically minded bro's & sis' will respond.
