Driver vent has cold a/c passenger does not


You can start by trying an actuator recalication.(w/o scan tool)

1. clear all DTCs by disconnecting the battery.

2. remove the HVAC/ECAS fuse for a minmum of 10 seconds.

3. install the HVAC/ECAS fuse.

4. start the vehicle.

5. Wait 40 seconds for the HVAC control module to self-calibrate.
If this doesnot work, probably the right actuator is defective. You
will have to replace it. In the center of the HVAC module, there are two actuators, one is on the top part of the module and the other one is Under. The right actuator is the top one.

After the battery runs down or is disconnected the heat or air conditioning vent selection does not work. Air only comes out the defroster.


Try this:
1. Place the ignition switch in the off position.
2. Remove the HVAC/ECAS fuse for 10 seconds or more. It's in the under hood fuse box. Put the temp in full cold.
3. Install the fuse.
4. Start the engine. DO NOT TOUCH THE HVAC CONTROLS FOR LESS THAN 45 SECONDS.
5. Have any codes cleared with a scan tool.
