Questionthe problem I am having is the rear blower is only working on high, both with the forward rear blower control and the rear blower control. I was also having trouble with the forward blowers mode 3 not working, but I was able to fix that by replacing the blower motor resistor. replacing the resistor fixed the front blower, but not the rear blower. With all the research that I have done I have not been able to locate a rear blower fan or a resistor for that matter.
My next step is to either replace one of the 40 amp fuses or the forward rear control switch in hopes that is the case, but I would like to get a second opinion on that. the fuse box in the cabin has a fuse for the rear blower,
Looking at the electrical diagrams in the repair manual the rear control seems to be completely linked up with the forward rear controls which would make sense to me to change the forward control
AnswerREAR BLOWER RESISTOR BLOCK
DESCRIPTION
The blower motor resistor has multiple resistor wires, each of which will change the resistance in the blower motor ground path to change the blower motor speed. The blower motor switch directs the ground path through the correct resistor wire to obtain the selected blower motor speed.
The rear blower motor resistor is not serviceable separately. The resistor is integral to the blower motor.
If the resistor block is faulty, it will be necessary to replace the complete blower motor assembly.
The blower motor resistor cannot be repaired and, if faulty or damaged, it must be replaced.
OPERATION
With the blower motor switch in the lowest speed position the ground path for the motor is applied through all of the resistor wires. Each higher speed selected with the blower motor switch applies the blower motor ground path through fewer of the resistor wires, increasing the blower motor speed. When the blower motor switch is in the highest speed position, the blower motor resistor is bypassed and the blower motor receives a direct path to ground.
