Thanks for the response, I'll try looking up the relays for the 810 when I get out of work. I think I have found a locally owned auto parts store that hires employees that know about cars, rather than the empoyees at autozone and kragens that didn't even know what a relay was.
I have a pic of the blower motor relay from a 1983 280zx. I don't know if it is the same in your 1980. Mine was mounted with two screws on the passenger side right up front.
I have a 1983 280zx (non-turbo) and the blower motor Relay (mounted under the passenger side dash) quit working right as the summer is starting. It is encased in a metal braket with four prongs in a rectangular pattern. I have tried various car part stores and websites, and they only have the under the hood relays. It has JIDECO and JAPAN molded into the white plastic and the following numbers stamped on the metal bracket:
C - 2977
MR3S -1101
Does anyone know where I can get the part? I appreciate any help and many thanks in advanced. It is getting hot here in Southern California.
