Since you probably have the A/C on 99% of the time, being in AZ and in traffic, why not have the fan run HIGH all the time.

Remove the 2-pin connector of the "Engine temp sensor" found a several inches ahead of the "Coolant temp sensor" and jumper it. This will trigger the aux fan relay which will make your aux fan run on HIGH all the time.

Another solution, bypass the RESISTOR, which keeps your aux fan running on LOW once a certain press is achieved within your A/C circuit. It's located right behind the left headlight under the ABS controller thingy. This would probably be better....

good luck,
