HVAC

Anyone have an issue where your A/C and Heater blower settings only work on low and high?

I have an Gen 2 V6 '07 Limited with electronic HVAC controls. Lost ability to control fan and modes. Fix was to replace control unit that's attached to ducting behind glove box. I've written it up and submitted, but haven't seen it posted yet. You've got different HVAC unit, but look at schematic for a resistor in the fan layout.

Sounds like the resistor block is bad,,,
