Dimmer switch doesn't work. Dash lights will brighten or dim without using switch. When they're bright it is so bright that the dash is blurred; when they are dim it is so dark they are nearly invisible.

At times, dimming will remain at same or change levels even after stopping and restarting engine. Doesn't matter the driving conditions...rain, bright sunshine, nighttime, tunnels, shade, dusk, dawn, snow; bumpy, smooth, wet, or dry roads; making turns left or right; stopping or starting in traffic.

Dealer says NPF and cannot replicate this concern.
