Im not an expert but I own a 1996 Mercury Cougar. I have similar problems which I can't find a solution. It started with dome light then trunk light then cruise control then brake lights then coolant fan. I've changed out the ccrm and that helped some of the problems for a short time. I rewired the brake and turn signals and dome lights. I think it all started from jumping another car and hooking the leads up straight. To me its has to be in the control module since it controls the multiple devices. If I ever find the solution I'll pass it on. Still I agree with you on the amount of people with these similar problems have not found someone with the right answer.
