W201

This morning I got in the my 190e and the radio was on, started OK, thought battery might be dead. Then turned on wipers, soon after smelled burning rubber, thought it might be coming from a construction site, only to find I could not turn off my wipers at the control stick-they are still on. It will not rotate, high beams work fine on and off, so do turn signals. So I have an electrical problem, I'll remove the cover to access the wiper, turn switch, no doubt, I'll see some major melt down there. Has anyone else had electrical problems with their 190e. I've just been driving this one for a week, I purchased it from a dealer with 97K. Where else should I be looking for problems that perhaps resulted in this issue I have this morning?

I had not driven my 190D in a couple of days and then the other evening when I went to town, I noticed that both the fuel guage and temp. guage had quit working. I just bought the car and drove it home a 1000 miles and everything worked great. I have not yet picked up a repair manual. Just wondering if someone could point me in the right direction to start troubleshooting this. Thanks.
