There is a problem with the fuse box as it is not providing power to the fuses.

The fuse box must be inspected.

Hello again,

Did you do the checks I suggested in your other post?

What have you done to check the voltages?

With a 12 volt testing light I checked both sides of the fuses number 41 and 39 neither side is working, but fuse 110 works fine no power from either fuse 41 or 39. Also with key in on position check the fuse box still no power.

Basically what is going on is there is no power at the fuse box to fuse 41 for the cigarette lighter and OBD port. The fuse 39 works the 12 volt on the dash no power at the fuse box either with fuses in or out.

I know, I read that before.

As I stated, you need to remove or look at the fuse block as the power comes from the fuse box itself. Once you get power back to the fuse box, you will have power to the connector.

I want to thank everyone for their help. I found out what the problem was when I had a new junction box installed two months ago. They put the wrong one in the truck all the numbers matched up except for the letters at the end. Mine was a CB they installed at FA which fuse 39 and 41 was deleted. Which meant no OBD port no cigarette lighter and no 12 volt auxiliary port on dash. Ordered a new one installed it everything is working fine. Thanks everyone for your help and support.
