No power to 4pin trailer light connector, low voltage only…

Customer Question
No power to 4pin...

No power to 4pin trailer light connector, low voltage only to Left turn signal.,

Mechanic's Assistant: Is the power loss consistent, or does it fluctuate?

It is consistent, I only get 2 to 3 volts with the left turn signal on, nothing with the right or tail lights on.

Mechanic's Assistant: What is the model/year of your Ford?

2001 Ford E 350 super duty extended

Mechanic's Assistant: Are you fixing your E-350 Super Duty yourself? What have you tried so far?

I tested the lights on the trailer with a direct 12 volt connection and they work. I checked the voltage to the 4 pin connector at the back of the van and got what I just told you and now I am looking for fuse diagram to check to see if weak or corroded fuses or?

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

No I thought you were the mechanic

First thing is you want to check fuse 14 in the fuse box under the hood, also check fuses 5 and 6 in the box under the hood. Check those fuses first then let me know. I can get wiring diagrams if needed. Thanks.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
