Ve dz passenger side heater prob

[hack1979]

Hi
I've got a VE clubbie with dual zone climate control. Had some issues with a broken blend door actuator, so replaced the broken unit. Big thanks to this forum for the how to strip the interior to get to them! When I do a blend door calibration all the actuators except one cycle through their range ok, but the passenger side temp door moves to the hot position but doesn't cycle back to cold.

I've tried a different actuator, left the battery disconnected and tried again but no joy, it keeps doing the same thing. All other functions are fine, just passenger side blend door.

Anyone got any ideas what to try next?

Cheers
Dan

Tried swapping it with one of the "working" actuators to see if that fixed it?

Yes tried old ones, new ones etc. it's weird, if I do the calibration with the actuator in my hand (not screwed in position), it cycles back and forth ok. If I calibrate with it screwed in position, it goes full hot and stays there. The blend door mechanism is free to move.

Can you take a picture of the actuator in place? Someone might spot something your missing

Sounds like its grounding out when screwed in but that is just a guess without seeing it
