heater prob?

my heater only works on high...i tryed switching out the switch and its not it ...what eles could it be? any ideas or thoughts would help ...thanks

blower motor might be going out.. my guess

the resister is done, its under the passenger side of the dash, attached to the heater box with 2 phillips screws

I'm agreeing with the above. Take out the glove box to find it.

It's not the blower motor, that only has two wires. Working only on high, where the voltage is not cut down, is a classic symptom of bad resistor.

thanks guys ill check that out ..

Now the blower resistor is only if the issue is that the blower motor runs only on high speed. I'm assuming that's the issue because you say you swapped out the switch itself.

Because if your issue was that the heat is always 100% hot, that would be different, like a bad cable, heat control switch, or diverter door. You didn't specify which switch you changed. Clearer explanations can oftentimes help.

the temp controle knob i deleted so its on hot at all times if i need ac ill roll the window down and ya its only working on hi ..i replaced the switch
