On a Pontiac Montana need to know where the location of the resistor that control the spee d of the motor

SOURCE: location of blower resistor

The 96 LeSabre Custom and LeSabre Limited use an electronic module in place of a blower resistor.
It is under the hood on the firewall on top of the heater plenum, but below the relay rack.
They tend to short and run on high until the module burns out and then it quits.
The same part is used on many high-end GM cars from 92 to 96. The electronic module has two connectors on it. (If yours has only one plug it is a real resistor pack and not electronic.)

The resistor is located on the blower housing on the firewall under the hood under the relay center boxes.

I beleive you need to change the Power Window Switches Module in the drivers side door panel, as these connections are interlinked within this module and it is usually the first part that fails. Especially that you already changed the switches & motor in the passenger door and it still does not work. Once you remove the dual switch module in the driver's side door, you will understand what I mean. Plus it is really easy to access. Good luck! I have the same model, Claude

The resistor block is normally located in the air box close to the blower motor for cooling.The fact you have no speeds on the blower indicates it might be a fuse. Have you checked them because this is where I would start first.Next step would be to check the blower motor itself.Remove it and give it 12 volts from the battery,it should want to twist out of your hand so hang on.Then I would pull the resistor block and check that.They are usually held in with two screws and if its done you should be able to see the burned out circuits with your eyes.Good luck
