rockfangd Posted August 19, 2016 Author Report Share Posted August 19, 2016 Ok so I decided to stop by my local yard today and picked up a actuator. I ended up disconnecting the battery for a few minutes, hooked it back up, turned the key on for 3 minutes and let it do its thing. It made a full sweep to hot, then a full sweep back to cold. I am not exactly sure as to when it is supposed to move but I will have to give it some time. AC was ice cold so I know that works. Noted the large gear was cracked on the old one. Apparently a common issue. Since replaced with nylon gear. A actuator setup I am used to will move the actuator in increments varying on where the temp control lever, or knob is set. But It seems on our Cadillacs it is set automatically by the system via whatever it feels it needs (basically if it is 40 and you want it to be 80 the door likely opens all the way)(but if you are warming or cooling slightly it only opens or closes a little) Also I did not see any ACM Data. Only codes and clear codes. Quote GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
