RPM and Oil gauge non functional

[tagoy]

I had my 100 car washed yesterday and these two gauges didn't function anymore. But the car ran safe drove 150km. Anyone here ever experienced this?

Also checked possible leaks in 3rd brake light area, pillars, and sunroof but no signs of water. Deiving me nuts!

Any help would be really appreciated. Thank you

I'd first check and make sure the two plugs behind the black panel with the dimmer switch are screwed in tight.

I had electrical problems after rain and car washes. It was the passenger front sunroof drain being clogged and letting water drip onto the computers in the passenger kick panel.
My gauges were staying live even with the key removed and the door locked.
Start there.
Open the sunroof, and using something small, like a pop bottle, pour water into the drain, then see if it comes out from under the truck. Mine did not, it came out under the dash.
Cleared the clog, problem solved.

Thabk you for the advice! Both drains working properly but double checked my rear cargo was wet. Will post pics on my suspected leak areas. (Sealed the 3rd brake light prior with silicone which i followed on one of the posts here)
