I have a 88 Mer. Marquis. My blinkers went out the same as my AC blower. Checked fuses. All good.?

Question

is there another fuse someplace that connects the two. The ac worked fine previously and so did the blinkers. They both went out at the same time. all lights, brakes work fine but no turn signals, front or back, just before the AC blower went, i turned the car on, and it didnt work. I turned it off, turned back on, and the ac came on. This happened a couple of times before it totally went blank. Radio works good, wipers, cruise not working. Any help appreciated.

Faulty main relay to control ignition,.
Usualy under the hood in the power distribution box.
