Here's a problem that I think is caused by a poor ground circuit.

When the driver's air conditioner is on and the headlight dimmer switch is activated the driver's air unit turns off. The headlamp bulbs have been updated, so I think it's possible the new bulbs are incorrectly wired or there is a loose or open ground circuit somewhere between the headlamps and the frame. Anyone at Prevost experienced this problem?

This problem was resolved. I had inadvertently turned off the battery switch which while driving causing a feedback in the circuits.
