As i line up lever and cable/rod to position on gears on actuator and have the temperature knob on say hot air full, as soon as I connect wire connector to actuator the actuator reverses temperature to opposite hot lever/rod/reverses or turns to cold. If I line up lever/rod to cold air with actuator on that position as soon as I connect wire harness, the actuator turns to opposite temperature.
Does this make any sense?

Yep it sounds like the actuator is bad becasue that got the polarity of the motor that is inside the actuator backwards.

Is it an OEM part?

Please let us know what happens.

Cheers, Ken

Hi Ken and thank you for replying. It is a part from a salvage yard, I did not thought about polarity

It could also be attempting to go through calibration which will send it to both extremes.

Hey Ken and WrenchTech
I finally got it working, the 12V motor was inverted in polarity, after cleaning and aligning gears and lever/shaft and temperature know the actuator dial position itself "home". I believe cleaning gears and using dielectric grease on the dial circuitry helped a great dial inside the actuator, knob controls temperature like a charm.
Thank you both, I will post pictures later to illustrate this problem better.
