I replaced the EGR now Temp guage is not working!! I don't know why??? I don't see any thing that I missed. Took the doghouse back apart and still don't see what the prob is.
ANY IDEAS?????

I show engine coolant sensor on front of left cylinder head.
Make sure it is still pluged in and no wires damaged and check ground wire in thermo stat area.
Also check fuses for gauges.

It was the sending unit...Replaced and now it is fine.
