Software problems of the 2002 Ford Windstar

I am the owner of a 2002 Ford Windstar. I bought the vehicle with 16,000 miles on it and it now has 104,000. I am current on all of the recalls issued by Ford as of June 2011. My abs light, and brake light have been coming on randomly throughout the course of driving during the day for the past 4 years. I live in florida. It is on always throughout the summer and less frequent during the winter months. I have had the computer updated with the latest software by Ford 3 years ago when the problem started occurring. . . Did nothing to help. I have taken it to the Ford dealership and local mechanic. Each have looked at it and have told me different things. The dealer suggested I needed a new electronic control module. ( I did the recall suggested by Ford and have the new wire harness on the van. It has done nothing to solve the problem of the abs light and brake light coming on) he says because of the heat it warms up and causes intermittent electrical connection in the unit because the fragile board is being stretched and malformed. The code most commonly scanned by professional mechanics is code c1185. The local mechanic (not Ford) test drove the van and found all kinds of abs codes coming up and sinks failing. I left it at his shop and the next morning he drove it again and the lights were off. He said it is a computer issue because everything doesn't just fail all at once and then no lights come on the next day in the a. M. Later that day when I took it home and it started to heat up in the summer time here in florida the lights came back on indicating to me that I had no anti-lock brakes!!!!! Ford needs to recall this part because it is a safety issue that we as customers have paid for and expect. Please look into this issue and do something!.
