Clean the CB and e-connectors, then apply a thin membrane of dielectrical grease, and on the bulb
metal jackets. Use a good circuit board cleaner like CRC. Look for any harness faults too. You also may have condensation in the under hood power box.

 

whats the CB LOL?

 

Its the Electronic Circuit Board inside the instrument cluster. LOL - back at chew
