first, i own a 1998 plymouth breeze.
well the problem is that a couple of days ago three of the four fan speeds went out. So this means that i can only use the high speed on the fan to make the a/c and heater work, the other lower speeds have no effect. Appreciate any suggestions
Most likely the blower motor knob is buggered. You should see if you can find a new heater controls unit and put it in and see if that fixes the problem.
