Look in the engine compartment, passenger side firewall. There will be a plastic box protruding from the firewall. A small wiring harness will be terminated on the tire-side of the plastic box. The terminals coming out from the box are the resistor pak. It is affixed inside the box with two small screws. The fan speeds are controlled through the use of resistors in the ground of the system. You have full-speed now because that speed is a direct connection to ground.
Hope this helps.....
