Ok~ended up doing trial and error on the Blower Motor relay location in an 86 Brat. I removed every relay behind the fuse box in the Brat one at a time to see what was affected.Results: found the relay for the headlights , (2 relays for that) the turn signals, the seatbelt warning lights, the intermittant wipers. And found no other relays there. So I went back under the hood & looked back where I started. I had one good/new square type relay that I switched out for the 3 available one at a time.The photos show what ended up being the relay for the blower motor~ it's a regular square type, actually pretty easy to find at a parts store. The fan works at all speeds now.First time in over two months~ I'm so happy!!
