97 GT Electrical issue

Greetings All,
The wife just called me and she was on her way to the store in her 97 GT (70k) when she noticed that her power windows didn't work.
After she got to the store, she found out that the car has lost the power windows, power door locks, interior lights and power to the radio. All of the other dash / console lights are fine as well as the headlights and tail lights. Engine is running fine.
All was well the last time she had it out.
I don't have any wiring diagrams for that car and thought I'd ask for ideas before I get home and dive in.
Thanks in advance.
 


Maybe a fuse? But if you said everything started working fine again later, that probably isn't it. I hear loose ground cables can produce electrical issues. I'm not sure where any ground cables are though.
 
check the connections to the bcm under the dash left side of the steering column. The interior lights and power locks go thru the bcm and i am sure i remember a bolt with a bunch of wires grounded around there as well you may have to look behind the kick panel or carpet to find it.
 
Thanks for the replies. I apologize as I gave the wrong impression this was an intermittent issue.
The problem just started yesterday. Everything was working fine up until that point. Just to clarify:
Power Windows , Power door locks, interior lights, and radio power no good.
All other dash / console lights, headlights and taillights good.
Engine starts and runs fine.
Thanks again.
 
Thanks all.
Been looking at it this morning. Was able to determine that all of the related fuses EXCEPT the power window fuse have power at the fuse.
The window problem may be a separate issue but coincidence is strange.
Had to stop for work and will continue tomorrow morning trying to find the grounds. Thanks again.
 


I have not found any loose wires or grounds so this morning I pulled out the body control module but read somewhere that there were different ones depending on whether or not the car had anti theft.
I don't know if this car has that or not as it had an aftermarket alarm installed by the dealer. The part numbers on the box are as follows: 10293827.
Also has 7249 REV Z2765 SEF M3 Red
Also on the large connector body itself, someone wrote 2-18 3A
Any thoughts to help get the right replacement would be appreciated. Thanks.
 
Hi all,
Does anyone know a source for a drawing of the BCM connections on this car? I really want to check a couple of more things before I spring for the BCM.
I pulled the RAP relay, tested it and it was fine.
Thanks.

There is a TON of super-useful info on that site for you to use. You can go down the rabbit hole there real easy.

Ok... have fun!
 
Greetings all,
After the great tip from SinisterFootwear for drawings, I was able to pretty well eliminate everything but the BCM. I got the replacement yesterday and it indeed solved all of the issues.
Thanks to all for the comments and help.
