1999 Jeep Grand Cherokee Blower Motor Resistor Wiring Diagram Database

It would be Off, Low, Medium, and High speed. Low speed passes through two resistors Medium speed passes through one resistor High speed by passes all resistors. Here is a pictorial view of an 84 Wiring diagram for the heater blower.. The main power feed is the single brown wire that connects to the blower terminal on the firewall below the battery. There is a three wire connector that plugs into the blower motor resistor which is inside the passenger compartment just above the passengers side fresh air vent, red with three pins sticking out. The blower motor body also needs a ground.

Pulled the old resistor, replaced with new resistor, same issue. I'd like to start at square one and work the diagnosis back from the fan motor to the switch, but I haven't found any schematics for the 06. Want to test all the connectors and wiring. diagrams or point me in the direction of previous discussions.. For this conversion, you will be removing the wires in your blower motor resistor harness connector (plug), and relocating them to match the diagram we have provided. We will assume you have already installed the new resistor onto the heater core housing for the purposes of these instructions. We suggest taking digital pictures of the wire position in the connector (plug) before starting as a.
