Default 1991 c1500 heater blower resistor

Hello, Friends! I may need to replace the Heater Blower Resistor. As the Resistor heats up in use, its values go out of tolerance and my new Blower Motor slows down. Just installed a new Blower motor, so its brushes are fresh.

Does snyone on-List know WHERE this Resistor module is located? My Haynes Book doesn't cover it, except for showing it on a Schematic. HELP!
Thanks, Sandy

It is under the dash behind the glove box. It is fairly easy to get to if you remove the glove box first. Check Youtube there are tutorials.
