Condition
General Motors has decided to conduct a Voluntary Emission Recall involving certain 2001-03 Chevrolet Silverado and GMC Sierra model vehicles,
equipped with a 4.3L V6 (RPO L35 - VIN W or RPO LU3 - VIN X) engine. The ignition distributor cap and rotor in these vehicles may corrode and

Malfunction Indicator Lamp (MIL).

Dealers are to inspect the distributor ignition ventilation holes and, if necessary, replace the distributor cap and rotor, remove the External Ignition
Protection (EIP) vent screens and install a foam sleeve around the A/C accumulator line.
