HelloCustomer the resistor must be cut from the case. The instructions are below.


  1. Negative Battery Cable.
  2. A/C control relay bracket with the relay and set off to the side.
  3. Blower resistor harness.
  4. Stud from dash panel.
  5. Cut the access cover from the case. It is necessary to cut all 4 sides to remove the 3 attaching screws. Use a sharp utility knife for cutting. Make the cuts straight and clean as the access cover must be reinstalled and is visible to the customer.
  6. Blower motor resistor.

Are there any wires to worry about when cutting? If so where are they located. How do I secure the panel back to the case when done?

Once you make the sut you can access the mounting bolts. After installing the new resistor put the plate back on and cover it with black silicone or weather strip adhesive. You do not need to worry about wiring.
