I'm new to this forum so I don't know if I'm posting this in the right place so if I'm not let me know. I have a 1994 Dodge Ram 1500 and I've been recently changing my dash lights and all that good stuff. I just got some T5 led's for my Air Conditioning controls. I made the mistake of trying to put it in while I still had the battery connected and the second the light touched, the dash cluster and the AC control lights went out and wont turn back on. Is this a fuse or did I mess up my cluster?

 

It's a fuse. Take a look at your fuse panel on the drivers side of your dash and you'll track it down in know time.

 

Cool, but I still cant figure out which fuse it is. Could it be the ILLUM fuse? (thanks in advance)

 

Get a multimeter out and set it for a continuity check (the beep check). Touch the little metal tops of each fuse and find out which one doesn't beep. Replace with the same amperage fuse.
