Ground location?
Anyone know where the ground location is for the Left Actuator in the HVAC system? I'm getting codes B0361H, and B0363H. First one is LEFT ACTUATOR FEEDBACK SHORT TO GROUND, and the second one is LEFT ACTUATOR FEEDBACK OPEN.
Just started having problems after replacing my battery yesterday. Before that, everything was fine. Now the HVAC doesn't work correctly. Cold air blows out from the drivers side, warm air from the passengers. The fan doesn't respond to commands from the control unit. It blows at the same speed constantly. It will switch where the air comes out correctly, face, feet, or defrost.(After I repaired the vacuum hose I broke replacing the battery)
Any help is greatly appreciated, thanks gang!

Why dont you try this? Clear the DTCs and see if it will work normaly again.
Here is the website to help you explain the DTC codes:
These are the absolute best C5 Diagnostic Trouble Code (DTC) web sites!!!
http://www.corvettedoctor.com/Code_Main.html
http://www.corvettedoctor.com/index.html
Go to “technical data base” and then to “Corvette ECM Computer Codes”. Then select your year car. Read the instructions and then scroll down to the "READ MORE" window to view the code definitions.\
Here is another very good site:
http://www.obd-codes.com/trouble_cod...d-ii-codes.php
Make sure to include the H or C suffix!!
Write down and post your DTC’s Then clear them ALL!

There has to be something wrong with that particular circuit. It say short to ground and also open to ground. I really need to find where this circuit grounds at so I can check that area for corrosion. I read your post about cleaning all the grounds(great information BTW) but still don't know where this one grounds at. I haven't got the time right now to clean each and every ground connection on the car. Using it for my DD at the moment(son needs my other car) and it gets pretty darn cold over the winter.
Any more assistance is greatly appreciated!

Im looking at the HVAC shhematic and here are ALL of the HVAC accociated grounds and what they are associated with and where they are at:
HVAC control head Connector D,,Pin 1
HVAC Fan Motor = G-202 Passengers foot well
AC Compressor Clutch= G-101 Eng Compt fender behind headlight module
According to the service manual, if you get B0361 Connector C, pin 8 of the HVAC PROGRAMMER MODULE (control head) and or pin 9 of the LEFT ACUTATOR is shorted.
According to the service manual, if you get B0363 Connector C, pin 8 of the HVAC PROGRAMMER MODULE (control head) and or pin 9 of the LEFT ACUTATOR is open.
I would remove the HVAC control module (Below the radio) and examine the wires and connectors, with the module out and disconnected, check the connectors, wires and harness going up to the left actuator.
Here is what the actuators look like on the drivers side:
Here is what the actuators look like on the passengers side:
Hope this helps.
