I have a 2005 chevy suburban that the rear ac stopped working on. I checked the RR HVAC FUSE and the IGN 3 fuse and they're good. I have power at the Orange wire at connector C2 and power at the Red wire going into the motor itself. I tested the motor with a seperate battery and it worked. I tested ground from the G410 to the motor red wire and the C2 orange wire and it was good; verified with resistance from G410 to ground and it's good. What am I missing?
Does anyone have any experience with this issue?

do you still get Freon to the back? Meaning the lines under the truck and the evaporator are getting cold? Is it just the blower motor that is not functioning? Do you have auto or manual controls? It could be the control module that is bad. Black box with the two plugs going to it. It is bolted to the rear HVAC plenum near the actuators.

Good question about the Freon; not sure. Manual controls. Do you know of a way to test the control module? Thanks for the reply.
