Where is the heater blower motor resistor loacated on a 1996

The blower motor relay is energized when the Blower Motor Control is set to the High position. This removes the blower motor resistors from the circuit and battery voltage is then applied directly from the HVAC BLO fuse (RH IP Accessory Wiring Junction Block) to the blower motor though the relay switch contacts. The blower motor then runs at high speed.

HVAC Blower Controls Circuit Description
The blower motor is a variable speed motor. The motor operates at a higher rate when voltage is increased to the maximum level.
The blower motor resistors reduce the voltage supplied from the A/C FAN fuse (LH IP Accessory Wiring Junction Block) when the blower control is set at low and medium speeds (speeds 1-4). The blower motor relay is energized when the Blower Motor Control is set to the High position. This removes the blower motor resistors from the circuit and battery voltage is then applied directly from the HVAC BLO fuse (RH IP Accessory Wiring Junction Block) to the blower motor though the relay switch contacts. The blower motor then runs at high speed.

It's part of the blower motor resistor assembly . right below the blower motor under right side of dash

There might not be any relay, Mary - it might be wired directly from the switch to the blower motor, although the lower blower speeds may go through a speed-reducing resistor pack to get there. If that's true, the resistor pack will be somewhere in the heater plenum, probably near the passenger's foot area.

If the blower doesn't run at all, check for voltage at the blower motor with a meter or test light, switch in all positions, keyswitch ON. The blower motor may have failed.

did all speeds stop working or does it have high only?
if none of the speeds are working then you need to verify you are getting voltage to the motor, if you have voltage the motor is out, no voltage check the heater control relay.
if it blows only on high then its the blower motor resistor located in the duct work under the dash around the glove box area

I would check the blower motor resistor. I believe it's mounted into the heater box.

replace the blower motor resistor located on the heater box were the blower motor is located the wiring to the blower may go to it. This is very easy to locate if you buy the part first.

Hi, sounds like your blower motor resistor needs to be replaced. If not the resistor, check the blower motor.

REPLACE A/C BLOWER RESISTOR.

It is usually located inside the fan housing, under the passenger side dash.

Check or have checked the blower motor resistor. This is usually how they act.
