My heater only blows on high - 1999 Mazda B-Series

Answers :

The heater blower resistor pack has failed and the only fix is to replace it.

I can't remember where it is on your model, but when you buy the part your Mazda dealer will provide you a print out diagram if you ask nicely. Most are fiddly to get to and usually the glovebox on most models must come out and often the lower dash shrouds. The resistor pack is fitted into the side or top of the fan blower box and just has a simple wiring plug and pone or two screws holding it in. Getting to the screws is usually the tricky bit!
