So I'm having an issue with my 02 Escalade. So my gauge cluster lights have went out. I checked every fuse I could think of. Everything was working fine. The turn signal/hazard lights on the cluster are also on. Everything else is working fine with no issues. I ended going to the junk yard and pulling 5 different dimmer switch boxes from Tahoes and Yukons and replaced them one by one and nothing seems to work. I finally found one from a same year Escalade as mine and it worked for about a month and now its back to being off. Has anyone encountered this problem before? Like I mentioned, everything is working as normal except the gauge cluster lights being off and the turn signal lights stay light on the dash. Any feedback would be greatly appreciated.
