Accepted Answer

Normally the problem on these vehicles is the a/c mode actuator. You can try to make the system recalibrate the actuators by disconnecting the battery for a few minutes and then reconnecting it. Start the vehicle but do not touch any of the a/c controls for about 3 minutes to let the system cycle all of the actuators. If this does not work, the mode actuator will need to be replaced.
