    Not sure how to explain this but I'll try my best here. If I turn the round knob to adjust temperature or turn up/down the fan, it moves the temp/fan multiple dials instead of one click at a time. The knob actually clicks once, but the fan would turn up 3 or 4 times. Anyone experience same issue and know how to fix this?

    The fan response is not direct with delta T, is is dynamic and proportional to the delta T commanded and the known system delta T response rate.

    Don’t expect a 1:1 response.

    sounds like you need a new knob, but idk what's involved

    the service manual is at techinfo.toyota.com
