Great Great great job! 99 Silverado Vortec V8. Same issue

[@JeannieSanders]

7/32 close to 5.5 mm works in a pinch good video

[@minx163]

Ha ha Thanks for the help in return we call them 5.5MM "SAE 7/32 "

There is a calibration that needs to be done so the new actuator can re~learn.

[@dylansmith3]

Where can I find the parts for the inner gears for the actuator

[@ermannodangelo1062]

You need to calibrate it before using.

Ok..on all videos I've seen..no one ever shows what position that the air is on when putting the mode actuator on..I notice on the mode actuator there are 3 markings..and the new one set in the middle. So then..what do you turn the air on..(vent, floor, defrost) before you plug the actuator in..

I think I know what you mean and if I'm remembering right, I had a hard time with that too. I don't remember what setting I had to have to get everything aligned correctly, but there was a lot of trial and error. It was a PITA 😅

I've been digging for the last 24 hrs for info to put mine back together. I removed the actuator off the cam and the cam off the blower box so all my alignment is screwed up...Anyways I saw another video where a guy installed a brand new delco actuator with cam and he said you need the mode set to "face vents" for it to be properly calibrated when you plug in the new actuator out of the box...

[@scottbeavers1713]

I’ve never seen anyone really remove it either. However, it is my understanding that the selection switch should be set to the middle position or straight up. I have to do this repair for my brother in law and I’m certain to f it up and never hear the end of it

[@dannyrios4654]

@@scottbeavers1713did having the switch in the middle work?

[@randy1203]

I'm not very clear, was the a/c resolved I've watched many videos that recalibrate the actuator! Did you get lucky and bypass that step?

[@stephenh.bunkybyrd2024]

I did it with 7/16 instead of a 5.5.
