  12. CHECK FOR BLOWER MOTOR FUNCTIONALITY WITH A TEST LIGHT IN PLACE OF THE BLOWER MOTOR NOTE: This step uses a test light to simulate normal circuit loads. Use only the test light recommended in the Special Tools table at the beginning of this section or equivalent. To avoid connector terminal damage, use the Flex Probe Kit for the test light probe connection to the vehicle. Do not use the test light probe directly on any connector. Ignition OFF. Disconnect: Blower Motor. Connect: Blower Motor Blower Motor C2004 C2004 Pin Circuit Measurement / Action Pin Circuit 1 CH402 (YE/GN) 2 VH301 (YE/BU) Ignition ON. Select panel mode with the blower motor on high. Does the test lamp illuminate? Yes: INSTALL a new blower motor. REFER to «Blower Motor»(ref-517581-S15823376372012121200000) . No: GO to 13 .
  13. CHECK THE BLOWER MOTOR GROUND CIRCUIT FOR AN OPEN Ignition OFF. Disconnect: Blower Motor Speed Control. Measure: Blower Motor Blower Motor Speed Control C2004 C271 Pin Circuit Measurement / Action Pin Circuit 2 VH301 (YE/BU) 2 VH301 (YE/BU) Is the resistance less than 3 ohms? Yes: GO to 14 .

Yes: INSTALL a new blower motor speed control. REFER to «Blower Motor Speed Control»(ref-517581-S21945767782012121200000) . If the concern is still present, GO to 17 . No: REPAIR the circuit.
  17. CHECK FOR CORRECT HVAC MODULE OPERATION Ignition OFF. Disconnect and inspect all HVAC module connectors. Repair: corrosion (install new connector or terminals - clean module pins) damaged or bent pins - install new terminals/pins pushed-out pins - install new pins as necessary Reconnect the HVAC module connectors. Make sure they seat and latch correctly. Operate the system and determine if the concern is still present. Is the concern still present? Yes: CHECK OASIS for any applicable TSBs . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new HVAC module. REFER to «Heating Ventilation Air Conditioning (HVAC) Module»(ref-517581-S13895863382012121200000) . No: The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
