Heater Problem

Forum: 

Hello i wonder if anybody can help me the heater in my sportrak
on speed one and two has stoped working.Normally it would'nt be a big problem but reading my service manual it says the engine
has a fast idle device which increases the engine idle speed slightly when the air conditioner system is in use and since my heater has stooped working the idle speed as slowed down it's more noticeable with the lights on at night.Can anyone help me with how i can fix the two speeds on the heater.Thanks Charley

Resistors.

Use this sites search facility and search for heater, resistor etc etc. There is at least one post explaining where to find the resistors and their replacement.
