The switch on the temperature lever is supposed to supply a ground to the trigger circuit on the fan relay.
Your heater should work fine without the aux fan operating except at idle speeds. The majority of the time the air is going to be supplied by the engine cooling fan.

There is an 8x connector nearby, look for a brown wire w/wht. stripe on it. That's your trigger wire (according to the manual).
