Ever since I remember, my instrument cluster lights stay at the same brightness, and cannot be adjusted. While it's at a good brightness, it can be a bit annoying. Can anyone tell me if there's a way to fix this?

the adjuster knob on the right side of the instrument binnacle surround... is it shorted?

its just a variostat, could be shorted out so the resistance part don't work.

hey this has happen to to.im a noobie so not really familiar with the terms. so can u elaborate what exactlyhas happenand how it can be rectified.thanks

So have you tried the dimmer roller switch and its not working correct..???:)

yeah no change

my guess is it occurred after you changed your head units?

hmmm males ense how can changing headunis result in this

quite simple really, theres a rheostat wire going to your head unit that allows your headlight switch to control the lighting in your original deck. This wire is obviously useless when you replace the deck with an aftermarket unit.

hmmm is der neway 2 rectify dis so i can adjust the cluter again
