Like i said in the title my dimmer switch isnt working but my gauge and HVAC works. i do have reverse indiglo gauges tho maybe thats y my cluster lights and HVAC is still working. if i hit any bumps or hit my steering wheel the light flickers. so im not sure if its the fuse or not. i check the fuses under steering wheel everything seems fine. im not sure if there are any other fuses i should check? or is the dimmer switch broken? probably something EZ to fix but im not no electric pro.
