Feeling Left In The Dark....Trying To Repair My GMII Module

Getting this thing on the ball now. After a couple of posts on the forums, you know my favorite (bimmerforums.com)
trying to find out why my interior lights were not working. My Visor lights would work but not the "map lights" and the rear lights
would not work. Now these lights are controled by something that i found to be called the GM. I did some research on it, it is also called the General Control Module as well as other names. From What i know there are a couple of versions. Mine is a GMIII
it is a 12v and the Part# on it reads 61.35-8 352 057 12- 373 10
Heres A pic


Now during a 2-day conversation with a friendly member from the forums (Chief Jimbo)
He kind of explains it to me, what it is how to fix it and what i would need to do. So basically what i have to do, simply is jump the circut. sounds simple enough ok so i get my tools out..

Heres what i used.
1 - My Trusty Soldering iron from Radio Shack
2 - 2 Kinds Of Solder One Is a light Duty Rosin Core Solder and the other is High-Tech Silver bearing solder
3 - A small allen key to get into the GM.
4 - A Pair Of Sissors
5 - Some 20 gauge speaker wire
6 -A Mini Light
7 -A New Sharp Razor

Ok So Here i start, embarking on another electronically dangerous journey I remove the 2 screws on each side of the GM
(total of 4 screws) Once i get it open i start to examine the board for burnt circuts or darkness, to sum it up any signs of a blown circut.
And indeed on the other side of the relays i find one, i took a pic so you can use it for reference


As you can see to the right side of the circut is burned, or you can say it has blown out.
The Prospect of jumping a circut is like driving down a road. Except use ypur imagination and lets say that the road has been blocked of, and now you find a another way around. or you create a new road to go around the blocked off road.

So i began fitting a piece of speaker wire to do the jump, after the first wire was fitted and soldered in
here is the result


The First wire fitted pretty good and was pretty easy to go on.
the second one was a litle harder because the surrounding were a bit tighter on it. But still i fitted the wire and in it went. heres a pic with both the wires fitted


Also heres a diagram explaining what i did.


So I when i went back out to test my work, i sloppily fitted the gm back up, attached back the rear - battery lead and the i went on to replace the 25amp fuse that kept blowing. But When I did that i got happy, but little did i know that happiness would only last a couple of seconds. The interior lights came on, stayed on for about 5 secs and then shut back off.
I didnt know what to do so i went back to the Drawing board.....

BRB WITH THE SOLOUTION

The Big Green 7 Gets Seafoamed

As A member of the forums on bimmerforums.com, theres been alot of talk about this seafoam thing and after hearing basically nothing but good results ive decided to try it. For about 2 days i did my research before doing any thing, being that i didnt want to do anything wrong or mess anything up. My Advice is you do yours too.

The First thing i did was get all of my tools/supplies together.
What you need?
1 -3 8oz cups
2 -A Funnel
3 -A 10" Socket
4 -a hose whose opening is 1/4
5 -your can of seafoam

Next Pop the hood and remove the engine cover, it is held in place by 4 10mm nuts (not you dont have to turn them all the way
whats attached to these nuts are basically attached to hooks that which if you turn them to hard they will break off the cover so gently turn them untill they come loose)
After that youll see your engine.

The Next thing to do is look towards the back part of the engine on your right hand top side (facing the engine)
for a sort of nozzle of port, heres a pic so you dont get confused, The Pic is kind of fuzzy, but theres a arrow pointing on the nozzle that your looking for


Heres a picture of the peice you were suppose to remove. Make sure you dont pull it off with pliers because if you do then you might put a hole in it


Once you find your nozzle take your hose and slide it on, it should slide right on, but if it doesnt dont panic, just make sure its pushed as far on as possible.
Heres a pic with the hose attached


The next thing to do is seperate the seafoam equally what i did was use 3 plastic cups and evened it out in all 3 ( i didnt have 3 cups one blew away so i used 2 cups emptied one in the bowl and then fill it up again, this made it even. heres a pic of that:


The bottle says to put 1/3 in the oil, 1/3 in the gas, and 1/3 in the air intake. All i did was put 1/3 in the oil heres a pic of that


Then i Turned on the car, They say you should have someone rev up the car up to about 2,000rpm. i didnt have anyone to do it with so i actually did it kind of ghetto, and used a stick to hold the pedal ( this is not advised) this was achieved by squeezing the stick between the seat and the pedal. (After putting down the e-brake.

After doing this then you want to slowly let the hose suck up the seafoam from the cup


take your time though because you dont want the car to stall. when it is almost done just let is suck up the rest of it, then immediately shut it off let the engine sit for 20mins, after 20 mins passed then start the car and enjoy the smoke show!
