HVAC module reset
Having an issue with the HVAC reset on my 2008.I could have sworn the reset option was on there when I worked on in last year but I don't see it on my TechII.I see the actuator calibration but not the module reset. Am I imagining things again?Tried the fuse pulling but no change.

This is what I have in my records:
To reset the HVAC control unit:
Press both defroster buttons and the fan speed up button together, all three at the same time. Acts like a soft reset for the system.

Thanks for the replies.I have tried just about everything but the mode valve actuator won't calibrate.The mode valve works manuallly so I know it is good.It tries to self calibrate when the ignition is turned on but it always goes back to defrost only.Tried a new actuator and another module I had but got the same results.Seems to be in the mode valve itself but I just replaced it in the spring.It acts like the actuator isn't reaching the limit to reverse it and calibrate.Guess I will just have to keep plugging away at it.
