Can We Fix it? 1999-2007 Silverado A/C Mode Actuator Repair

[@minx163]

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

[@nexrace]

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

[@garysimmons5520]

Even on the 99 silverado without the auto temp control?

[@JeannieSanders]

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

[@adrianreyes4702]

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

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

[@bobcatculv3574]

Wish I knew the brand of the brush guard.

[@richardwagoner1225]

Where did you find the gear set? I can't find any.

[@jnorth568]

I was kind of hoping that those alignment marks you were talking about on the gears were a little more visible😢 seems to be a lot of different marks on those gears and they're not synonymous in manufacturing

[@allove70]

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..

[@bernierubbersgarage6066]

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?

[@ermannodangelo1062]

You need to calibrate it before using.

Where did you get a RHD Silverado?

[@jnorth568]

The license plate says Texas 😂😂😂

[@stephenh.bunkybyrd2024]

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