Battery Cable problems of the 1996 Dodge Caravan

In 2003 bcm replaced for my windshield wipers would not operate. Over $600 . Last year my battery cables and battery were smoking and I was lucky I got to the dealer just in time as black smoke was gushing out from under my hood. . . . Another $600 repair. In January 2006 electrical system craziness. Check engine light was on and it could not be smoged. They reprogrammed the module and I was able to get it smoged 2 days later the check engine light came on and the car would turn over and die . . . . I returned and was told I needed a pcm module replaced $719. Getting the car back was one electrical mishap after another. . . . The gauges went crazy. . . Taken back to dealer. . . . Reprogrammed . . . . And then told they were not sure how to fix it. . . Then got the car back and the clock and radio intermittently went on and off. . The computer shutting down and not allowing the remote to open the locks using the key the alarm would go off and I could not shut it off until the computer came back on and I could use the remote. . . . I was then told by the service manager that I needed a body control module(bcm) which I replaced in 2003. He was nasty and rude. I told the general manager I really did not believe they knew what they were doing . . . . For each time I brought the car in with one problem they returned it to me with another. He could also not guarantee that if I paid another $550 for a new bcm that it would solve all the problems. . . . . . . After 6 weeks and four trips to the dealer having my car over 2 weeks I was frustrated and angry. . . . And after reading on the internet countless other Dodge Caravan owners have the same problems I am outraged Dodge has ignored its responsibility to its consumers. . When I dropped it off the clock, radio, locks and alarm were the problem. . But an hour after I picked it up it started raining and guess what. . . . The windshield wipers were not operating.
