'95 525iT, no crank, no start, no power windows, sunroof or doorlocks,

[632 Regal]

NOW, I still DO NOT have any power windows, door locks, sunroof, or windshield wipers (they only work on high).
It is a different part number than what REALOEM states it should be. The people at Bavarian Auto Recycling told me they were all the same.

Look up what the new modules number is for, google, ebay etc to narrow down what year and stuff. According to Shoguns reply it might in fact not be the one you need. Bavauto just scraps and sells used crap, they do not know everything about everything.

Glad to hear she runs! At least your off to a good start.

I obtained two other GM's and a replacement RM. Engine still starts, but STILL no power door locks, windows or sunroof. can't open rear hatch (wagon) windshield wipers function only on high speed without the park function.

Thanks for the help. The replacement part number is 61 35 8 355 817. I'm not sure of the original part no. The green case fell apart in my hand when I first tried to remove it. I never found the pieces with the part no.

That part number is from a E34, I found some in the net: GM BMW E34 61358355817. And my BMW ETK says: Recondioned part no. for the part # 61358355817 is part # 61358359538.Part 61358359538 (AT-Basic module) was found on the following vehicles: E34: 525i Touring, 525i, 530i Touring,4 530i,535i, 540i, E34 M5 3.6, 518i, 518i Touring,520i Touring, 520i, 524td, 525ix Touring, 525ix, 525td, 525td Touring,525tds, 525tds Touring, M5 Touring, M5 3.6, M5 3.8.

I personally believe the GM is not only the problem, maybe part of it. But if it helped to replaced the GM (although this is strange to me with that problem you have), I would dig more in that area under rear seat in the electric lines, connections for corrosion, broken wires etc. Has there ever been water under the rear seat?
AND the area rear door (tailgate) wire loom!: in your first post you mentioned:
Found broken rear window heater wires.
Found faulty micro-switch at rear window lock, failed closed (making relay module click repeatedly)
Measured 3.5+/- amp draw on battery even with the above repaired
The RH tailgate wiring harness at tailgate is good, but I haven't cut the loom to check the LH tailgate harness.

The tailgate problem is also not 100% solved, start there first. BOTH sides wire looms.

I spent 1/2 day today digging around under the rear seat power dist box. I found corrosion in a group of 4-red/white wires. I cut them back to good wire and soldered them together. This seemed to have fixed the radio. confirmed with wiring diagrams those were for the stereo system.

Two other bunches of small gage, crimped wires looked suspicious, so I soldered them also. I'm not sure what they went to. No other functions returned.

I sprayed the GM connectors with contact cleaner, and cleaned the RM connections with a small pick.

I've removed and cleaned all the grounds I could find under the rear seat. They were all in great shape to begin with.

Yep there has been water under rear seat. Yesterday, I removed both front seats and rear section of carpet. the carpet was very wet. The front carpet was dry. Everything is dry now.

The tailgate issues have all been sorted out. I cut the LH and RH wiring looms at the tailgate and all wires were perfect.

I haven't measured for any current draw lately.

Thanks for the help.

Just to give you an idea where all the wires are UNDER the carpet, pics when we parted a 1988 E32 750iL http://www.bimmerboard.com/forums/posts/270025/

My current draw is down to 0.23 amps. I've at least done something right.

Armed with pages from the electrical diagrams and my multi-meter, I found TWO MORE corroded spliced connections under the rear seat power distribution box. I totally missed these yesterday. I had to cut the wires back a couple of inches to find good, clean copper to solder.

ITS BACK! ITS ALL BACK!!!!! EVERYTHING WORKS AS IT SHOULD!!!!!!!!!!!!!!!!!!!!!!!!!!!!

One good benefit of my nearly month-long efforts, is that I got a GM with one-touch-down power windows. Plus some perfectly good GM's and a relay module to sell.

Thanks everyone.

The moral of the story is that if all fuse links are good, and all other crap is good, THEN THERE ARE CORRODED CRIMPED CONNECTIONS UNDER THE REAR POWER DISTROBUTION BOX.

Holy crap. I'm tired.

Now to pack and head back to my day job two states away. (driving my Nissan truck)

Great news! I never heard of corroded wires back there, any clue why the carpet is getting wet back there?

Nice work! Glad to hear it.

Quite often found, especially when the sunroof drain hoses are blocked or the drain holes under the doors are clogged and the water cannot drain out, so it finds a new way into the car.
Also there could be mislocated rubber plugs in the chassis under the carpet (the rubber plugs are from chassis paiting process, after the paiting process these plugs come into because the whole raw chassis went thru a painting 'bath' and then the paint had to be drained out of the chassis.
On the E32 even leaking taillight or trunk lid gaskets can cause this, the water finds it's way from trunk to the area when the ZKE components and battery are under the rear seat. Maybe also same on E34.

Ever had a look under the spare tire? Maybe you have a small swimming pool in there.

In any case you have to find the leak, otherwise you will have the same problem again.

It can also leak in in the front if these drain holes are clogged http://i44.servimg.com/u/f44/14/94/56/00/ablauf10.jpg
