RECIRCULATION Control Motor Does Not Operate Doors

WARNING: This page is about a different car, the 1999 Acura 3.0CL and 1999 Acura 2.3CL. However, it is still accessible from the selected car via links, so may be relevant.
  1. Check fuse No. 8 (7.5-amp) in underdash fuse/relay block. If fuse is blown, replace fuse. If necessary, repair short to ground. If fuse is okay, disconnect recirculation control motor 4-pin connector. Turn ignition on. Check for voltage between ground and terminal No. 1 (Black/Yellow wire) of recirculation control motor 4-pin connector. If battery voltage does not exist, repair open wire between fuse No. 8 and recirculation control motor.
  2. If battery voltage exists, turn ignition off. Test recirculation control motor. See RECIRCULATION CONTROL MOTOR  under TESTING. If motor is okay, go to step  4 . If motor is not okay, remove recirculation control motor. See RECIRCULATION CONTROL MOTOR  under REMOVAL & INSTALLATION.
  3. Check recirculation control linkage and doors for smooth operation. If linkage and doors are okay, replace recirculation control motor. If linkage and doors are not okay, repair control linkage and doors.
  4. Remove stereo unit and disconnect climate control unit 20-pin connector. Individually check for continuity between ground and terminal No. 4 (Green/Red wire) and No. 3 (Green/White wire) of climate control unit 20-pin connector. See Figure . If continuity exists, repair shorted wire(s) between recirculation control motor and climate control unit.
  5. If continuity does not exist, individually check for voltage between ground and terminals No. 4 (Green/Red wire) and No. 3 (Green/White wire) of climate control unit 20-pin connector. See Figure . If voltage exists, repair short to power in wire(s) between recirculation control motor and climate control unit. If short to power exists, climate control unit must be replaced.
  6. If voltage does not exist, check for continuity in Green/White wire and Green/Red wire between recirculation control motor 4-pin connector and climate control unit 20-pin connector. If continuity does not exist, repair open in wire(s) between recirculation control motor and climate control unit.
  7. If continuity exists, check for loose wires or poor connections at climate control unit 20-pin connector and recirculation control motor 4-pin connector. If connections are okay, substitute known-good climate control unit and recheck. If symptom does not exist after substituting known-good climate control unit, replace original climate control unit.
