I took the blend door actuator off of my 2000 zr2 blazer and it has a 6 pin terminal. All the new ones that i can find have either 4 pins (manual) or a 5 pin (electronic). Im kinda stuck because on my 6 pin factory actuator my positive pin is the far right pin. On the 4 pin model doesnt even have a pin where the positive is on my 6 pin. I ordered a 'gm' one off rockauto that is supposed to fit but the pins are wrong. What to do. I could fix the gear on my factory unit and reuse although I don't want to put one back on that's 25 years old. Anybody?
