Dash lights not working

[dblack]

My dash lights seem to be working intermittently.

Was driving in the rain with lights in auto and wipers on. Dash lights were on, looked down and they were off, but headlights were still on.

Stopped truck, cut it off and the dash lights came back on. Cranked it back up, dash lights went off. Doesn't matter what setting I put the headlight dial on the dash lights won't turn on, so it's not like they are off because the headlights are off. Headlights are on...

Any ideas?

The IPC brightness level is determined based on the ambient light sensor, not just the position of the headlamp switch.

The IPC brightness level is determined based on the ambient light sensor, not just the position of the headlamp switch.

It seems backwards though. They seem full brightness at dark and very dimly lit during the day.
