Okay

Can I start by getting the VIN and any stored codes in the computer?

I’m currently not with the truck but there are no codes

Ok no problem. What size [engine](/topics-engine-ford/) do you have?

6.8 V10

Ok thank you. Lets go after one thing at a time. Which one would you like to start with?

What do you mean

You said "the gauge cluster is not no speedo, tach, oil, fuel, coolant gauge plus my overdrive and fog lights do not work "

what do we need to start with

I would like to know which problem you would like to address first?

My gauges aren't working

Sounds good. Is this problem constant or intermittent?

Constant

Ok and the [alternator](/topics-alternator-ford/) is charging when the engine is running?

I guess so, the whole truck hasn't died in two days

Ok got it, thank you. Fuse 45 in the central junction box (inside the vehicle) powers up the overdrive cancel switch. If you are SURE this fuse is good, remove the steering column covers to access the wiring for the Overdrive cancel switch in the end of the shift lever. Inspect the wiring for any signs that the wiring could intermittently short out. Repair the wiring or replace the shift lever as needed and recheck operation. If that checks out good and you are SURE the other fuses are good, you could have a bad instrument cluster. You would need to remove the instrument cluster and check all powers and grounds going to the cluster with the key on. By the way, fuse 43 also powers up the fog lamp circuit

I will try that thank you for your time

Still needing help

I can help

First do you still need the vin??

That would be great

Stand by1FMNU43S22EB96930I still have the same issue

OK so what are we fine we ran the test above?

I did replace the OD switch and check fuse 43 still nothing

OK does this fuse to blow? Did you check or replace the harness?

No fuses blown and the wiring harness from the OD button to the plug in yes I did replace but not from plug to where they go

OK have you checked the inputs to the instrument cluster like I mentioned above?

I have not but how is that tied into the fog lights and OD switch??

I do believe it gets powered up by the same circuit the other components do. You may wanna either remove the cluster and check the inputs on that wire coming from the fuse 43 or check the overdrive switch for power.

Okay that will take some time and out of curiosity what does relay 306 do??

Unfortunately I cannot look it up by the number. I will need to know what circuit it powers up in order to pull wire diagram

That relay powers up your power windows and some other components

Okay, looks like I have some work to do so thank you for your time again

You bet! You're welcome
