Review on Dorman 973 000 Blower Motor Resistor by Troy Larson

Buick Regal 2000; high fan speeds worked, but lower ones didn't. I installed a Dorman 973000 resistor and now all speeds work. The resistor was hard to find and had to be removed with a mirror to find the 2/4 mounting screws. The resistor is located under the passenger side dash, between the fan motor and almost opposite (1/4" gap) the interior firewall/floor. There is a red wire coming out of the fan motor, trace it forward and it connects to the fan. Resistor. The two mounting screws closest to the fan motor must be removed. The two mounting screws on the side of the firewall should be loosened just enough to allow the resistor to slip out of the mounting screws and then removed; these two Screws are not visible and were found by touch; do not remove them completely on the Buick Regal 00.
