Rear Glass Release Inoperative: Roadmaster
- Shift transmission to Park. Backprobe Remote Control Door Lock Receiver (RCDLR) connector C1 with a test light between terminal "C" (Light Green wire) and ground.
- If test light does not light, check for poor connection at transmission position switch or open circuit in Light Green wire. If connection and wire are okay, replace transmission position switch.
- If test light lights, check for poor connection at RCDLR connector C1 terminal "C" (Light Green wire), RCDLR connector C2 terminal "B" (Dark Blue wire), or open circuit in Dark Blue wire. If connections and wire are okay, program a known-good transmitter. If rear glass release operates, transmitter was defective. If release is still inoperative, replace RCDLR.
