Lost power to aux switches

[luvmybronco]

Not sure if anyone else has had this problem but I lost power to all of my Aux Switches. I’m using #5 for rear lights & #6 for Air Compressor. Last night I was going to use the rear lights and when I went to flip the switch, the blue light turned off instead of turning amber. Same with the Air Compressor. Tried all switches and all go from blue to nothing. Anyone else have this issue? TIA

No issues here. I know the individual switches are fused, not sure if there's a main aux switch fuse?

Do you have the #5 & 6 going to a relay? They are only 5 amp switches on their own.

Suppost to be 10 amps. I thought the aux switches were already relayed. The rear lights are 15 watts and #6 for air compressor is just a trigger wire. The air compressor is wired to battery

I just checked for power at the fuses and I’m not getting any power to any of them. I’m only using 5 & 6. Not sure why 1-4 not having power either

If no power at the individual fuses there must be a main aux fuse. Are the individual fuses still good?

yep, pulled all of them. None are blown

That's a head scratcher. @flip may be able to help with a wiring diagram.

Correct @luvmybronco, they are 10 amps.

Is there something in ForScan that enables the switches? Last thing I did, was use ForScan to enable the amp for the sub. Actually, I think the rear lights were working after that. Not sure what is going on. Even if I wired 5 & 6 wrong, the other 1-4 are on different circuits.

Was working on before I got caught with an extended phone call. If fuse F2 (10A) in the BCM is good, my guess is the accessory delay relay may have an issue which requires the BCM to be replaced.

There's going to need to be some testing done to see where you have and don't have power so pull the driver A-pillar trim to get to the green wire on that harness or pull the overhead console to see if you have power on the green wire. No power, then follow back down to BCM.

Thanks Flip. F2 is what I have my GMRS radio tied into with an add a fuse link. I guess it jarred loose. Put the fuse in the back spot of the add a fuse link and now everything is working as should. So now we know.
