2020 Peterbilt 579

I have a 20 579 it’s got 6 guages on dash, manifold,oil temp,2 suspension load guages and two diff temp guages. The 2 diff temp and suspension #2 guage aren’t working it l they light up but don’t read. The other 3 work fine any ideas?????

 

You should be able to move the gauges around and they work in any position.
I’d give the jumpers a good wiggle and see if they start working. If not, then move a working gauge to a non working position.

I’ll try that thanks. The bottom middle and two on left will not read but have a light

 

Look at your rear ends make sure the wire to sensor is their and hooked up.

 

They are there and hooked up
