Acc fuse

[elpasorabo]

Hey team 77 K10. My accessory fuse keeps blowing. What all is that powering so I can run down where I have a short?

I would check the cigarette lighter first, especially if it’s been used to run constant 12V to various accessories.

Lighter, dome light, also clock and power door locks (if equipped).

Thanks. So mine is a real basic truck without a lot of options so sounds like my cig lighter or my dome light. I appreciate your help.

A trouble shooting hint:

The cigarette lighter is hard wired to the fuse block but the power lead for the dome light circuit is a plug -in type. You might want to just unplug the dome lights and see if the problem goes away. If it does, you'll know where to start looking.
