I have a first gen, but this might be applicable to you. One day, it was raining, and I was using the windshield wipers (obviously.) Since I have a two hour round-trip commute, I noticed that they started acting funny, wiping sporadically. Over the length of the trip, I noticed that the problem only got worse, and I noticed a slight burning smell. When I got home, I completely forgot about it until I left for work that night. When I switched on the lights, only my high beams would work, no matter how many times I switched from high to low. Occasionally, the lights would go completely off. I remembered reading on this forum that such a problem was indicative of a failure of the multi-function switch (read: turn signal thingie.) I had to replace it, and the part was about $120 from a local Dodge dealership. Good luck in finding out what the cause of your problem is.
