Daughters bug....
We have a 2004 diesel bug. Last week while driving my daughter had the low beam, heater and wipers die on her. The fuse box at the battery is good. Is there a common ground? or did all the modules get fried at the same time? Not sure how to check the modules or is there a common module for all three of these items? Also the signal indicators went out.

Sounds to me like the ignition switch.

Headlight bulb is most likely not related to anything other than just a burned out bulb and/or overheated wiring for the bulb. These cars do not dim the headlight bulbs enough for DRL and they burn out OFTEN. Your other bulb will be burning out very soon as well. Always replace in pairs. I think the 2004 did not have HID, you should have standard H1 halogen bulbs.

As for wipers and heater, start with fuses and do not rule out other simple issues. I assume when you mean the heater does not work you are referring to the blower? There are air blend door problems with these cars as well as thermostat issues.
