I installed a sony head unit using the quick connectors and now my dash lights dont work. Whats up?

Either that sending unit is bad too or the guage in the dash needs replacing

You may have damaged the instrument cluster. The PCM has to receive a code from the instrument panel to start. Its part of the security system. Beyond checking fuses you are going to have to take it to a qualified mechanic with the proper diagnostic equipment. It sounds like you wired something incorrectly

Please tell me the problem with the lights as this year doesn't have any headlight relay, The most common problem is that the headlight switch gets hot and burns out along with the connector to it, both must be replaced as one repair. Solder and shrink tube the new headlight switch connector on, DO NOT use "crimp" connectors or the problem will occur again very quickly. The dash panel that is over the switch is easy to remove, just remove lower dash panel and then main panel screws and it comes right off.

All lights, or just your illumination lights? Illumination: bulbs need replacing. All lights; SERIOUS problem. There is a dash panel fuse on car. check that. Has anyone done any work recently under dash( like installing a radio)? May be they accidentally pulled a connector loose behind dash. Need to pull your instrument cluster to check that. Usually two big connectors with lots of wires going to back of instrument cluster. If no power at all with key on: check under hood at power distribution center for a main big fuse out.

it is most likely the turn signal flasher unit is faulty & needs to be replaced, you should find it under the dash on the drivers side it could be a square or round unit with a connector plug on the top, when you remove the connector plug the unit has three terminals on it.......hope this helps......cheers.

While at the junk yard pick up a used insturment cluster . Cost about $20 bucks .

Did you use the factory ground when you installed the stereo? If you did thats your problem, the factory grounds on dodges act really weird, ground your stereo directly to the chassis (metal dash support under the dash) your problem will likely go away.

you have a bad lighting control module. $499 new, $250 from tascafordparts.com or less from ebay or car-part.com.

It is under dash above brake pedal.

Problem is the Turn Signal "FLASHER" unit, 1.Turn on Emergency FLASHERS 2. Go under Dash while they are on Listen -for Clicking sound then feel for it 3.
