I have a 1988 Mazda B2200. The heater fan only works in the highest position and does not work in any other position. Any ideas on what the problem and solution is. Is it a resister block and if so where do I find it?

Highly possible on the resistor.
However, I am not much on Mazda's but I believe that it would be somewhere near the blower motor on the plenum chamber.

Good luck

go to www.mazdarecycling.com for all your Mazda needs. They were very helpful to me.

Remove the blove box and it is behind the duct to the right vent in the housing of the blower motor.
