My son just got a 1988 Mazda b2200 as his first car. The blower for the ac/heat doesn't work. He's replaced all the fuses he's found. Anyone have any ideas?
I have the same truck. Mine only worked on high. I replaced the blower motor resistor and it worked for a few seconds and then the resistor started to overheat and fry. I then removed the blower motor and found it to be pretty seized up so I replaced it along with another resistor and it works great. At any rate, be careful not to ruin a new resistor. If it shows any signs of getting hot when you first fire it up then turn off the blower motor immediately and replace it too. In my case, the worn out blower motor is probably what caused the original resistor and the replacement to fail in the first place.
Just bought 1989 and had the blower motor replaced; it works only on the two highest settings now (as opposed to none!). Although it does defrost the windshield OK, there is not a whole lot of heat coming out. Would replacing the resistor help, or is the lack of heat more likely to be caused by something else?

Mine only works on the two highest settings. I heard that the actual switch in the dash goes bad. Maybe check that, they are pretty cheap.
