If you are having problems with your fan only running at 1 or 2 speeds, it's not a relay. It's the resistor block in the firewall on the passenger side of car.
It is pushed into the firewall (not bolted). It has resistors on the back that often go bad. The plug that plugs into it is often in bad shape too. The dealer can get just the plug and pigtail to splice in, and the resistor pack. It took me a long time to locate this problem and repair it!!![/i]
