Dodge - Grandcaravan :: 2014 - Car Is Making Clicking Noises When Turn The Key

I have a 2006 Dodge Grand Caravan. Back in November 2014 my car began giving me trouble starting, making clicking noises when I turn the key. My mechanic told me I needed an alternator so I had him install one. A few weeks after that I had the same problem. He told me a wire leading to the alternator was bad and he replaced it. A few weeks after that the exact same thing happened. He said another wire was bad. I asked him to check all the wires, which he says he did. Back in June of this year my car started giving me problems starting again. Every now and then it would click when I turned the ignition key. Finally, I went back to my mechanic and this time he said I needed a new starter. This was July. Then, last week, my battery light came on while I was driving. Long story short, I had to replace my alternator again. It's only been 9 months! Coupled with all this, both my back lights are out; my right turn signal is out, most of the time, every now and then it works, and sometimes my windshield wipers won't come on.
