Hi there. Welcome to our site.
A bad BCM (located under the right side of the steering column under dash) may indeed cause the issue with the lights and wipers. However, the A/C clutch not kicking in might be another matter. Do you have access to a OBD-I scan tool capable of communicating with the BCM?
I'm sorry if you misunderstood both the way the site works, as well as my initial response in which I ask you if you have access to a scan tool that can communicate with the BCM. My intention was to guide you through the necessary procedures to diagnose and solve the issues you list - to that effect, I even pointed you to where the BCM is located.
At this point, I feel I'm not the right person to work with you, so I'll opt out of the question and re-opened to the field. Please don't reply until another expert responds or the question will be reverted to me.
