Control Assembly: Application and ID

CAUTION: Do not use bulbs that have a higher candle power than the bulb listed in the Bulb Application Table. Damage to lamp can result.

When illumination goes out in the Electronic Instrument Cluster (EIC) the complete button module must be replaced. The Mechanical Instrument Cluster (MIC) uses PC194 bulbs for illumination.

When changing lamp bulbs check the socket for corrosion. If corrosion is present, clean it with a wire brush and coat the inside of the socket lightly with Mopar Multi-purpose grease or equivalent.
