I have a 94 Toyota pickup recently the left side light was replaced after seeing that the side light worked the dash lights stopped working they will not come on or dim down or brighten could it be the switch that has stopped working the fuse does not seem to be blown.

 

It is a good possibility, but with out doing any checks with a meter, you could just be throwing parts at it. I would want to at least make sure I was getting power to the switch before replacing it.
