Control Panel Calibration Procedure On Vintage Air Gen IV systems using factory controls, it is necessary to calibrate the system to your specific control panel. This procedure ensures that the stroke of your control panel levers or knobs is translated into precise control of the fan speed, temperature blend and mode door position. Please carefully read and understand these procedures before beginning. The procedure may be repeated as many times as necessary to get it right. In preparation for calibration, you will need to attach the supplied white ground jumper wire to a suitable chassis ground. This jumper wire must be easily connected to the gray programming wire located in the main Gen IV wiring harness next to the relays. During the calibration procedure, you will connect the white jumper to the gray program wire, which will teach the Gen IV ECU the upper limits of the control levers or knobs. The blower will momentarily change speeds, signaling that the upper limits have been learned. You will move the levers or knobs to opposite extreme positions of their travel and then disconnect the white jumper. The blower will again change speeds, signaling that the lower limits have been learned and that the calibration procedure is complete.

START Control Panel Calibration Procedure (Cont.) 1. Turn on the ignition switch (Do not start the engine). OFF ON 2. Move the control levers/knobs to the position shown. DEF AIR FAN HEAT. Connect the white jumper wire to the gray program wire. Wait for the blower speed to change (Approximately 5 seconds). 4. Move the control levers/knobs to the positions shown. DEF AIR FAN HEAT 5. Disconnect the white jumper wire from the gray program wire. The blower speed will change, indicating completion of the calibration procedure. 1 6. Confirm proper operation of controls. Repeat procedure if necessary. When finished, tape over program wire connector with electrical tape to prevent accidental contact with chassis ground. 90271 REV D 4/1/15, 1967-72 CHEV P-UP wo AC CONTROL PANEL KIT PG 1 OF 16

OPERATION OF CONTROLS NOTE: CONTROLS MUST BE CALIBRATED FOR PROPER OPERATION. THE TEMPERATURE LEVER TOGGLES BETWEEN A/C AND HEAT MODES. FOR A/C MODE SLIDE THE TEMPERATURE LEVER ALL THE WAY LEFT TO ENGAGE THE COMPRESSOR, THEN MOVE THE LEVER TO SELECT THE DESIRED TEMPERATURE. FOR HEAT MODE SLIDE THE LEVER RIGHT TO DISENGAGE THE COMPRESSOR, THEN MOVE THE LEVER TO SELECT DESIRED TEMPERATURE. NOTE: EACH TIME THE SYSTEM TOGGLES BETWEEN MODES, THE BLOWER WILL MOMENTARILY CHANGE SPEEDS. ALL SWITCHES ARE VARIABLE BETWEEN POSITIONS, SYSTEM WILL PERFORM A BLEND BETWEEN THE FUNCTIONS.
