04 Sonata weird electrical problems
I have a '04 Sonata 2.7 w/ some strange electrical problems. They aren't show stoppers but a bit annoying. I got this car back from my ex (long story, please don't ask) and have found the following problems:
Any help is appreciated and I thank you in advance. |

Re: 04 Sonata weird electrical problems
Did the severed wires look like they were done on purpose? I'm a mechanic and given the first part you wrote about just getting it back makes me think someone went in there and cut and/or switched some wires around for fun. Does the trunk open light on dash go off when the trunk is open? If not I would follow the wires and look for a rubbed through wire, it sounds like it is shorting to ground, which could also be in the trunk switch its self which would explain why it goes off when you pull the bulb out, that would open the circuit. As for the door open dome light check the peg in the door it should be at the front or hinge part of your door. when you open the door it should pop out closing the circuit and allowing the light to come on, so if it is not popping out that would cause that problem, you can lube it up and get it to work again. Sorry never had to work on any remote door unlocks but again I would check for some damaged wires or something covering the the remote sensing device. Let me know if any of this is helpful, I have alot more you can check if it doesn't.

Re: 04 Sonata weird electrical problems
I have a 2002 Sonata GLS with similar problems. The main one is with the doorlocks. The doorlocks will lock both with the manual button and the keyless entry FOB, but will not unlock with either. When I press the UNLOCK button on the FOB the front and back lights flash, indicating the system is receiving the signal to unlock the doors, but nothing happens. If I unlock the driver's door with the ignition key and press the manual UNLOCK button, still nothing happens. If I press the manual LOCK button on the driver's door, all doors that are unlocked will lock. I suspect that fixing the problem with the driver's door UNLOCK button will also fix the keyless entry problem. Any opinions out there?
