WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  . For wiring diagrams, see WIRING DIAGRAMS  . Perform TEST VER-1 after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting any module connector.
  1. Remove key from ignition switch. Gain access to Remote Keyless Entry (RKE) module. See Figure . Disconnect RKE module Black connector. Go to next step.
  2. Using DRB, in ohmmeter mode, check resistance of RKE module Black connector terminal "H" (Black wire). If resistance is more than 5 ohms, repair open Black wire. If resistance is less than 5 ohms, go to next step.
  3. Connect jumper wire between RKE module Black connector terminals "G" (Pink/Black wire) and "H" (Black wire). Depress left front door lock switch. If left front door lock operates, replace RKE module. If left front door lock does not operate, go to next step.
  4. Remove jumper cable. Using DRB in voltmeter mode, check voltage on RKE module Black connector terminal "A" (Pink wire). If voltage is less than 10 volts, repair open Pink wire. If voltage is more than 10 volts, go to next step.
  5. Check voltage on RKE module Black connector terminal "C" (Orange/White wire). Depress door lock switch to LOCK position. If voltage is less than 10 volts, repair open Orange/White wire. If voltage is more than 10 volts, go to next step.
  6. Check voltage on RKE module Black connector terminal "E" (Pink/Violet wire). Depress door lock switch to UNLOCK position. If voltage is less than 10 volts, repair open Pink/Violet wire). If voltage is more than 10 volts, go to next step.
  7. Reconnect RKE module Black connector. Check voltage on RKE module Black connector terminal "G" (Pink/Black wire). Depress door lock switch to UNLOCK position. If voltage is less than 10 volts, replace RKE module. If voltage is more than 10 volts, go to next step.
  8. Remove left front door trim panel. Disconnect left front door lock motor connector. Using DRB in voltmeter mode, check voltage on left front door lock motor connector terminal No. 1 (Orange/Black wire). Depress door lock switch to LOCK position. If voltage is less than 10 volts, repair open Orange/Black wire. If voltage is more than 10 volts, go to next step.
  9. Check voltage on door lock motor connector terminal No. 2 (Pink/Violet wire). Depress door lock switch to UNLOCK position. If voltage is less than 10 volts, repair open Pink/Violet wire. If voltage is more than 10 volts, replace door lock motor.
