Lost my dash lights yesterday.

I just replaced my vacuum switch on the heater/A/C control box and all of a sudden my instrument panel lights and the overhead light strip that shines on the gauges aren’t lighting up. The vacuum had to be replaced because it had physically broken but prior to that I never had any electrical issues.

I checked all fuses and none were blown. Where should I start troubleshooting or does this sound like it’s a short?
