1970 part identification. Blower relay?

[sitruc]

(1970 thunderbird)I think this is a a blower relay, but can't find another like it. It had a fuse on top of it that is replaceable. Its rubber mounted to firewall and has a ground wire that mounts to firewall also. What is this thing?

That is more like the master relay for the HVAC system (and maybe other systems too?).

It is supposed to be a 7.5 Amp fuse on there. The actual hi-blower relay is on the passenger-side fender somewhere near the resistor block. The cars with manual HVACs do not seem to have this relay.

For about 20USD you can get the 1970 Ford repair manual. It's almost a must-have.

Thanks for the info, big help. I have the manual but it just says relay assembly. I found this thing I wonder if it's a replacement but doesn't have fuse?

I also noticed when the fuse is removed or blown on this thing, only the blower fan stops working.
