I lost aux power to the hole aux. All 4 fuses are good but no power to any of the 4 fuses. All wiring is good. All fuses in fuse box are all good and working good just no power to cig liter and did used a light tester on all fuses and the 4 around the aux1 don't work at all can't figure it out. As to why there is no power to them 4 I'm stumped everything around and underneath the truck looks good all grounds appear to be grounded good. What else can I look for?

Hi,

If you lost power to aux 1 and aux 2, it sounds like the fuse box itself is bad. There are no fused circuits before them in the box. See pic 1 below.

If you look at pic 2, I highlighted the auxiliary fuses for the power ports. Are these the ones that have no power to them? If they are, disconnect the battery and remove the fuse box. Inspect wiring, connections, and for damage of any type.

Let me know what you find. Also, you indicated four fuses with no power. Looking at pic 2 below, which numbers are they?

Take care,

Joe

Thank you for your response. Yes, the power is out on aux 1 and the fuses in front of it but I will give you more details when I get home from work this afternoon. Again thank you.

Hi,

Sounds good. Let me know as much as you can. If you do get the chance to check the fuse box, let me know that as well.

Take care,

Joe
