Presto! No turn signals, fuel gauge or radiator fan

'81 FI 2000. Noticed temp gauge creeping over 190 (radiator fan doesn't kick on), then noticed fuel gauge not functioning. Finally, no turn signals. All happening at the same time? Where do I start?

those are all on different circuits, so my best guess is grounds. faulty, corroded and loose grounds.

Where is the radiator fan ground located?

I'd check the fuse box first for loose fuses, then look at the ignition switch connector

Thanks y'all. It was a fuse. I think problem may be an aftermarket radio
