Ok so I searched the forum and found similar threads about the whole gauge cluster not lighting up or any interior lights at all. I checked the ROOM and METER fuses but the fuses were fine.

My problem is that I noticed the other day that my Gauge cluster including the Tach, Speedo, Oil Pressure, Water Temp, and Fuel gauges does not light up. The warning indicators and turn signal indicators and such are all working. My aftermarket gauges are also not illuminating. I do not believe it is a problem with the aftermarket gauge wiring as they have been working perfectly for years. Could it be the dimmer switch has gone bad?

Any help would be greatly appreciated.

 

You might want to see if your tail lights are working and check that fuse.

 

Good call, the tail lights are definitely not working. When I read the other threads some people said their tail lights were not working as well. I stupidly assumed they meant the brake lights which, when I checked, did work fine. I will have to check tomorrow if the fuse for the tail blew out. Will have to check the wiring back there as well as I just replaced the tail light housings with 99 spec style ones and see if there is something wrong with the tail light wiring harness even though I didn't mess with it.

Came back to edit this real quick, pretty sure I checked the tail fuse earlier and it was fine. Will replace it just to be sure but could it be the TNS relay? I have problems sometimes when water is directed into the engine bay by accident and the headlight relay goes nuts making the headlights do the whole "disco lights" thing by going up and down randomly when water is trapped in the relay box. I just washed the car a few days ago and it did the disco lights thing a little but I just pulled the retractor fuse and gave it time to dry. Maybe this could have messed up the TNS relay, will have to try pulling both and cleaning the terminals to see if that works.

 

check your dimmer switch, maybe that failed on you.

 

It was the TNS Relay. Old one was corroded as hell inside, had ordered some new ones off ebay and as soon as I replaced the old one all the gauge cluster lights and the tail lights worked.
