Kept getting code B0361. Tried all the tricks of pulling fuses, clearing codes and disconnecting the battery, checking refrugerant level. None of the tricks worked. Today I decided to pull the dash and remove the actuator. I ordered the actuator and am now waiting for it to come in. If the does not fix the warm air coming out of the drivers side vents does any know what else could be wrong?

 

If you open the actuator, you'll probably find the large gear cracked.

 

Please post pictures from behind the dash. I would love to have them for reference.

 

this forum has great info from people who have taken the time to document their repairs

for this issue see http://forums.corvetteforum.com/c5-t...actuators.html

and more info I clipped from another thread (didn't copy name of poster)

To inititalize, Bill Curlee says
There suppose to be self calibrating. Try this:

Turn the HVAC control head to OFF. In the DIC, pull up the HVAC DTC and clear ALL of the. When you hit clear, you should hear the actuators actuate and cycle thru its/their range. Do this until the DTCs no longer return. Turn the system ON and test.


and another approach I clipped from another thread (didn't copy name of poster)


As for the feedback pot alignment, I used my ohmmeter and measured the resistance between the 2 pins on the elec connector that are by themselves (2 on one side and 3 on the other).
With meter set to "Kohms", I measured 0 to 8 kohms while spinning the feedback pot. Positioned it so it was reading 4 kohms and installed the large gear at its' midpoint in travel. This sets both their midpoints and apparently got them in sync.

When attempting to install the actuator, the blend door shaft wanted to be in the full cold position, so I had to open-up the actuator again, remove center gear, and reposition the large gear (without disengaging the teeth with the pot gear) to the "cold" position.

Installed the 2 mounting screws, connected elec connector, reset codes and walahhhh, got a good initialization on the first try.

Cycled desired temp from 60 to 90 a few times being careful to rotate **** very slowly (rumor is if it's turned too fast, it freaks out the controller).

 

Yeah, I've had the 361 363 codes and this was the cause. Clearing the codes caused it to re-sync on its own, but the codes came back right away and from this picture, its obvious why.

 

Just what I needed
