New member here, could use some help

Hello to everyone in this great forum. This past june I bought me a 95 audi 90. Pearl color . 70k miles on it. Everything was going good with it until it started heating up on me this october. The fan wouldn't turn on no more. I found out it doesn't have a relay radiator fan and a relay radiator fan (speed 1). I'm looking for both relays but I wan't to know if they are both the same or is there any difference? doesn't anyone know where to find them?  Thanks to anyone who can help.
