hello everyone.. i have a 200 clk 430.. i was driving last week and my wipers are fine.. but this week it ended up not working along with my turn signals as well as my trunk release in my car and the trunk remote stopped.. can you guys give me some ideas on how to fix it or any ideas that might cause the problem.. you can email me at aroreiro@yahoo.com.. im trying to avoid going to the dealer for this eventhough my service b is up this weekend.. thanks in advance
