Hi;
If it is not the relay, it could very possibly be the resistor.
The resistor is located on the heater and A/C blower motor housing.
The housing is on the firewall "passengers side".
You will need to unbolt and set aside the
(1) speed control servo. (1) 10 mm Bolt - Easy
(2) coolant/washer reservoir. (2) 10 mm Bolts on the passengers side fender well. - Easy
>>>>The reservoirs (2) bottom bolts connected to the wheel well are a real PAIN IN THE A$$ to remove !!!!<<<<
I would suggest applying strong penetrating oil or "Liquid Wrench" to these two bolts.
Once the speed control servo and coolant/washer reservoir are out of the way, you will have a good view of the heater and A/C blower motor housing on the firewall passengers side.
You will see a black rectangular shaped resistor mounted to the housing, just below the vent tube input.
The resistor has a black connector with red and black wires and three small wires.
Disconnect the harness connector after the resistor is unbolted. You will find it much easier to disconnect it this way.
Remove the two small 8 mm hex head screws.
Pull the resistor out of the heater and A/C housing plenum.
Disconnect the black wiring harness.
Reverse instructions for re-assembly.
This information is right from the repair DVD
Blower Motor Switch Resistor
• The assembly is located on the evaporator housing in the engine compartment.
• Three resistance elements are mounted on the resistor board to provide four blower motor speeds.
• Depending on the heater blower motor switch position, series resistance is added or bypassed in the blower motor circuit to decrease or increase blower motor speed.
• An overheating protective device (thermal limiter) will open the resistor coil circuit when the temperature reaches 121°C (250°F) interrupting the blower motor operation in all speeds except HI.
• The thermal limiter cannot be reset and is not serviceable.
The resistor new will run about $12.00...
or a visit to the junk yard for short money.
I hope this information helps.
Good luck;
Rick
