Test 82A - All Doors (W/ RKE) Except LF Fail To Lock & Unlock

WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, 1995 Dodge Caravan, and 1995 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Always turn ignition off prior to disconnecting or connecting any module connector.
  1. Remove door unlock relay (third relay from right, bottom row) from micro relay center, located behind center console. Using scan tool in ohmmeter mode, check resistance of unlock relay connector (Pink/Black wire). If resistance is more than 10 ohms, repair open Pink/Black wire. If resistance is less than 10 ohms, go to next step.
  2. Check resistance of both ground circuits (Black wires) at unlock relay connector. If resistance on either wire is more than 5 ohms, repair appropriate open Black wire. If resistance is less than 5 ohms on both wires, replace unlock relay.
