A headlight switch problem in a Dodge Neon (2000-2005) is an easy repair job.
The same replacement procedure also works in PT Cruisers.
The headlight switch also controls the wiper, fog lamps, and turn signals.
The first thing to do is to buy a compatible switch assembly to replace the old one. It can be bought most anywhere such as an auto part store, eBay, and Amazon.

Steps to Replace Dodge Neon Headlight Switch (2000-2005)
1… Disconnect the battery.
2… Two screws need to be removed from the shroud covering the switch. They are located underneath at the bottom of the shroud and use a Phillips screw driver to remove them.
3… After the shroud is removed two torx screw need to be removed from the switch itself.
4… Disconnect the wiring harnesses tied to the switch. There is a small clip that snaps back and the harness pulls out.
Pop the clip out before pulling on the wire harnesses.
5… The entire old light switch assembly can now be removed.
6… The new light switch assembly will need the old windshield wiper switch to be attached. It is simple to do by removing two torx screws. Once the screws are removed it simply slides out.
