Hi, I recently bought a 2001 Amazon 100 series, 4.2 D, 170k miles, I thought this was the most reliable and rugged vehicle that will hopefully last me a long time to come. A few minor issues with the car, the Haynes manual I bought doesn't cover the main issue I have with the car and hopefully I will find a solution on this forum.

What is the issue you are having?

AC is either Lo or hot, in auto the fan speed is continuously high, I suspect its the interior temperature sensor, the wiring diagram shows it as a thermistor symbol, but not sure how to test it.

Thanks
