The real question is why the switches aren't working. When you first install them, do they work, and then quit after a while, or do they not turn the fan on at the right time straight out of the box?

If the switches work for a while then die, check your wiring. The switch drives a relay. Perhaps the relay died at some time, and somebody wired the switch to drive the fan directly. If so, the load of the fan will kill the switch in short order.

If the switches just aren't coming on at the right temperature, there may be some blockage in the radiator.

You could just wire the fan to run whenever the ignition is on. The fan only helps when the car is stopped or moving very slowly; after about 20 mph the windflow over the radiator is what counts. There is a relay that turns the fan on. In 1988 the relay had a time-delay off. The relay was enabled when the ignition is turned on, but stays enabled for 5 or 10 minutes AFTER the ignition is turned off. This allows the fan to keep running if the radiator is really hot. These relays have been known to fail on, and the result is a run-down battery. There is a fix that replaces the relay with one that shuts off immediately. But my guess is someone killed their battery with a bum relay, and instead of fixing it, just pulled it out and jumpered it so the switch drives the fan directly. Fix that, and your problem will go away.

See the Townsend Imports site for schematics of the fan system.
