"99 HVAC" Code??
Checked DIC...shows "99 HVAC - 1 CODE". I'm assuming it has something to do with the A/C or Heater...neither of which i'm having any problems with. Anyone know what it means??

B0361 Left Actuator Feedback Short to GND
CIRCUIT DESCRIPTION
The HVAC Control Assembly receives a LH electric actuator position signal from the LH electric actuator. The LH electric actuator position sensor is a potentiometer that is tied to a 5 volt reference source through CKT 1791 and to ground through CKT 1798, both from the HVAC Control Assembly. The variable output from the potentiometer feeds back a position signal through CKT 733 to a pull-up resistor located in the HVAC Control Assembly. This signal is used to determine the necessary drive signal to the LH electric actuator motor to provide the proper air mix door position. This value is stored in the Keep Alive Memory (KAM) portion of the HVAC Control Assembly.

Are you sure it's not blowing warmer out your drivers side vent?
Pull the battery cable and see if it clears it. if not, your actuator is probably in need of reindexing.
