Body Control Module ?

OK here's the final solution. (for Me)

My symptoms were
passengers side power lock started acting up.
The wife said that the dash went dead for a couple seconds but cleared up.
( i resoldered the cluster before)
then it was acting like it had a low battery in the morning.
I hit it with the charger and it seemed OK for a week or so.
I took it to Sears had the battery checked.
its was OK and I watched him do a load test it was OK too.
then one day at the post offiice it wouldn't start.
I went and jumped it got it home and that was it no more start even with a jump.


What I did
cleaned the posts connectors
pulled the started and made sure it was OK
ran down the ground to the block cleaned it up.
It wouldn't do anything even with a boost on the battery.
it did seem as if there wans't enough power getting to the BCM or the starter, clicking relays etc.
So this morning i got a bunch of info printed out and was going to tackle it and find where the power was not getting thru.

But like i nsaid in my last post i was going to take the battery back to have it checked out again.
Got to start from #1 right.
Well its shot it had 13 volts but when he did a load test this time it went to less that a volt and recovered a about 6 volts.
BINGO

So I got home buttoned everything up installed the battery
TA DAAAA


Started right up.
calibreted the ac/fan and its done

going to let the Missus run it a couple days and see if it throws any codes.
If it does I'll post.

OK
there's still some problems.
The dash works gauges wise, but no night lighting.
Headlights work
no turn signals
no hazards
no radio
brake lights YES
running lights in rear PASSENGERS SIDE ONLY.
I checked all the fuses under the dash.
Any suggestions?

Will pull the dash tomorrow and see what up with the lights.

I got out today at the crsck of noon to tackle the tail light problem.
So no running lights on the drivers side.
BTW the turn signals work
I have the scematic but this is my weak link.

I checked the bulbs they are OK
(looks like below is for the turn signals?)
then checked voltage
grn/red to blk 0 volts
wht/tan to blk 0 volts

I checked the black to make sure it was grounded it was.

so this is where i will need some help.

So am i safe in assuming that the running lights get all their power from the combo relay?

What do i need to check?

Thanks

Nevermind...
was looking at the schem and say that the left side gets it power from the same source as the lic. plate light..
i never noticed it wasn't on because the rear door was open while i was worknig back there.
So i had no lic plate light

checked the fuse and it was bad changed it and they are working.
