Speedo not working

All of a sudden today my Speedo, indicators, daytime running lights, and clock stopped working and gas gauge fluctuating. All fuses good. Before I go throwing parts at this where should I look? Cluster??

 

What year and engine/transmission?

When you say indicators you mean turn signals or all indicators in the cluster?
Does the tach and temp gauge work?

 

2005 4.0 6 speed
Yes the turn singles don’t work. They will blink with the emergency flashers on but not with the turn singles (both on dash and lights not working) Tach and temp gauge seem to be working fine.

 

What year?
Any other warning lights on?
Any recent work done?

Sorry for all the questions but I'm trying to determine how it's all related.

 

Just had the timing chain done a few weeks ago. Replaced the coolant temp sensor both vvt’s, cam and crank shaft sensors. Was still throwing a code for a faulty cam sensor and wouldn’t clear after replacing it again. Truck ran fine so I just ignored it for now. I haven’t got a chance to scan it after today’s issues.

 

Truck has over 400,000 kilometers on it

 

Looking at wiring diagrams I can't see how it's all related but since you say it all quit at once I'd say start with checking powers and grounds at something relatively simple like the clock or turn signal flasher.
I can't find a pinout for the clock but you should be able to go by wire colors.

 

Pins 7, 11, 13, and 14 for the clock

 

I’m not the best with wiring diagrams but I’ll try and figure it out. The clock only died for a couple hours and is working fine again.

 

Since you have a manual you could also check for power on the pink wire at the vehicle speed sensor on the transmission, I suspect you have a connection issue on one of the interior junction connectors but I can't be sure.
Have you had any water leaks in the cab that you know of?
