VW Jetta 2002 lights on alarm and door alarm not working
The warning alarm doesn't go off if I leave the headlights on after I have stopped the car, or if the door is open when the car is running. I have checked all the fuses and they appear to be okay. Please advise. Thanks in advance.

You need to have the VW dealer or a well equipped VW savvy repair shop scan the body control module (or whatever VW calls it) and see what codes return, it is likely the problem, but hold on you can't jut pop one in it must be programmed for your car.
The audio part of the alarm will stop after about a minute but the lights will continue to flash and the starter will be disabled until you use the key to shut it off by putting it in the door and unlocking it
Alarm box is behind the abs light panel and headlight switch, Its kind of hard to get to but there will be a 6 pin and a 10 pin, the other box is for the headlights, unplug the 10 pin harness and pit a jumper wire from the red wire to the red/black wire. Alarm is bypassed
ok so the same thing just happened with my jetta. So heres what worked for me: take off the door panel (drivers side) and you should see some melted or bunched wires together. just snip them and leave them be. It was either the wires or the sensor that messed everything up. This should work.
Open the driver’s door.With a screwdriver or equivalent trip the latch on the door 2 clicks so it is in the locked position, just under that finger get a can of Brakecleen and hose the snot out of it.I mean really firehouse it.As fast as it evaporates I still had it running out of the door drains.Be careful not to get cleaner on the plastic door panel, trust me take extra care. Open the outside door handle to release the latch, then open and shut the door for a while, like a few dozen times, to work the latch.Repeat as necessary.Follow up by shooting some PB Blaster, WD-40 or whatever light lube is handy. If this doesn’t work, give it might take a day or so to work free.If still nothing then the micro switch might actually be broken, but this usually does the trick
The sensor is in the door panel itself. The only fix I've found is to dismantle the door to replace the circuit board/sensor contained near the outside door handle. My 02 Jetta hasn't dinges for a few years now.
The door latch located in the door panel has a micro switch built into it assembly. It is what detects an open door. A new latch is about $150. If you could find a shop to replace it for you. You could also try buying some plastic-safe contact cleaner/lubricant and spraying the latch assembly out and opening/closing the door a few times to work it in.
