Wiper problems of the 2001 Volkswagen Golf

I have a 2001 vw Golf GLS. One day my car's truck door can not be locked, I took it to vw dealership for inspection. Initially I though it was just some wiring problem, but after the certified vw technician checked every possible things that caused the truck lock malfunction, it was so called "comfort control module" not sending signal and electricity to the truck lock. No big deal, it's just a truck lock, no need to worry, so I refused the $900 estimated repair amount for a new comfort control module (ccm) replacement. The vw technician further explained that it was ok not to replace it if it is just the truck lock malfunction, but if anything that is acting funny such as windshield wipers not moving, doors lock by itself, power windows can not roll down, or dashboard light going on and off by itself, then it is important to replace it. No major problem for a year, then suddenly driving in the rain at night, the windshield wipers malfunction, they will not move at all. I can barely see what was in front of me in high speed on freeway in the rain. I tried to open the windows so I can see better so that I can pull over safely. I tried to lower the windows , but the windows didn't come down. I slowed down and pulled over by guessing, luckily no car was behind me or next to me. I got out and checked if there was anything wrong or what obstructing the windshield wipers. I found nothing, it just simply stop working along with my power windows. I went to the dealer after the rain and again they were caused by the malfunction ccm. Since it is not safe to drive a car without a pair of functional windshield wipers and windows, I was recommended to have the ccm replaced. I went online and found that many vw owners have some similar ccm complaints and concerns and I personally think that the ccm is a big safety concern, this is why I am filing this complaint to see if it can minimize the danger and safety.
