Actuator problem or something else?

[hugox_89]

I have a 2002 TB LTZ with the digital climate control module.
I had the front vent actuator problem for a long time, a month ago I changed the actuator and my problem got solved.
Yesterday the clicking started sounding again so I shut the AC off. When started the truck again no air would come out of the front vents, only the dash and feet. When doing the calibration of actuators the front vents blow for like 5 seconds then it blows back again into the dash vents. Should I get a new actuator or could this be something else. I feel like something is causing the actator to go bad. Could this be the climate control module? Help please!!

Exactly which actuator did you replace? (There are 5 actuators in there) Not at all uncommon for them to be failing after maybe 17 years! I also have an 02. The gears inside are plastic and that plastic is getting old. Here in this thread are a couple of pictures of what can be happening inside.

No air out front vent after battery disconnect.

U did research and understand the situation. I'm just not sure which and how to remove the right actuator. My manual says it's the one further up but everyone Seems to be replacing the one closer. I changed modes and the one closer is the one ticking. My other question is how to get it out...

It's not the CC module. I'd say your mode actuator is toast again. Hope you didn't buy a Dorman as their electronics are suspect at best.
