If you can find the datasheets all the semiconductors (or at least the transistors) on the Internet then reverse engineering it should be easy.
Another thing is, are you sure it's gone wrong? Have you checkd for bad connections elsewhere and are sure that it's not the motors on the headlights or anything like that.
Thats where I first began to look, here are the steps I took to diagnose and end up where I am at now.
Apply 12 volts to motors.
Pass
Verify that 12V is being transfered from RCM (RCM absent) Connection to Motors
Pass
Verify that Signal 12V is being transfered from switch in car to RCM Connection
Pass
Verify that 12V is going from RCM to motors
FAIL
I will admit that this is approaching the limits of my electrical knowledge, but I joined this forum so that I could learn from the experience and knowledge of others, and expand my own knowledge. I have always been fascinated by circuitry and how things work. I wanted to take a basic circuitry class but the college I attend doesn't offer it or any thing near it. So now for the stupid questions.

i have given tentative component numbers and perhaps The Mad Electrician can try to check and create a component list and post it. for that purpose i created a notepad list for him to fill up. both are attached.
How do I go about doing this? How do i identify (what they are) the individual components. I know the basics, resistor, capacitor, diode, etc. How do I break it down further than that?
By the way the only thing I have yet to do as far as testing goes is to finger the relays and see if they are still good. But there is no visible corrosion.
Thanks to everyone for helping me, and thanks in advance for putting up with my stupid questions.
