Mechanic's tip
A dome light that stays on while driving, or a battery that keeps dying overnight, often traces back to a stuck door switch. Try spraying the switch with electrical contact cleaner first — corrosion on the plunger is common and often fixes it. Driver's door switches fail most often due to higher usage. The switch itself is usually inexpensive; cost varies by how embedded it is in the door jamb.
