Dodge Repair Questions? Ask a Mechanic for Answers ASAP
have you checked/replaced the bulbs yet?
what's your skill level can you read and follow a wiring diagram and use a test lamp and digital ohm meter?
no there are different bulbs for reverse, turn and brake the PARK lamps are on the same filament, I would check the bulbs first, the bulbs are all the same, yes even the reverse is a dual filament bulb, so you can swap them around for testing, if there is a bad bulb be sure you use the same bulb number or you will still get a lamp out warning
I will need the vin to pull a wiring diagram, and see how the system is wired, in my experience though corroded splices are more common especially in salt belt states
