Hello and thanks for looking at my problem. My system blows hot and cold, fan works on all settings, digital readout works and I can set temp acrross it's full range. The outflow is stuck on the dash vents. The readout shows the proper icon when I switch to vent, floor, defrost, etc., but the flow stays only through the dash. I did the digital diagnostic tree and ended with the message "mode door motor harness connector is disconnected". Is this something a normal human can do or is it a "take out the dashboard and steering column" type of thing? Also, where can I find a diagram or something to show me where this harness is?
