Actually I think "A" is powered by the ETACS, and keeps the windows active by leaving the relay on.
- Fake Don.. ;)
Who’s this – Fake Don guy …. He’s not one of those Fake exspurts is he? :unsure::D

Only thing I’ll add is I think “A” is also a ground, that is switched on/off by ETACS to activate window relay and it actual uses the ETACS hard ground at “B” triangle when it switches on the ground.

An actual expert can correct me if wrong. ;)

Edit: By the way I’m doing well….. except maybe for mental issues. :p

Actually, now that I think about it, I said "powered", and not providing +12.

Also, I think both A and B are necessary for the ETACS to be able to control the window when the key is off and the ETACS timer is running.

Only A is necessary when the key is in the ON or ACCESSORIES position?

Just trying to understand...

The way I see it power ~12 volts is supplied to pin 5 & pin 1 of relay as per your diagram. ETACS is activated by ignition switch and makes an internal ground connection between “A” from pin 3 to hard ground “B” closing relay and supplying power to windows. When switch is turned off ETACS uses its constant power from fusible link 6, to hold ground closed internally until its timer runs out, then opens ground disabling windows. This process is what allows you to still roll down windows for short period after turning key off, unless a door is opened which immediately disables windows. So A & B are always needed no matter the key position.

I’m sure you can follow this by noticing “A” Blue/yellow wire continues to next page diagram dealing with ETACS. The “A” is missing in the pdf format but you’ll see “power windows relay” and the wire is missing the Y but the L for blue is there. It goes to the ETACS (pin# also missing) but you can see internal transistor, timer and internal ground. If you look at pin 57/59 it feeds to “B” triangle which is same as one on page you supplied.

Thank You Don.
If I haven't mentioned it in the past (pretty sure I have) that I am a (retired) Software Engineer, with just enough knowledge of electrical/electronics to get me in trouble.

I am always eager to learn and listen to those who are more skilled than I.
I continue to try to help members, and I always love when are REALLY knowledgeable members step in and give their insight.

This forum is NOT dead, some of it's members are LONG TIME (ie older). I am not surprised to see them (and A LOT of younger technically savvy) are still hanging around.

Bob.

Yeah I should has said that better. The ETACS doesn't "power" any of this. Power is from fuse link 9.
When the key is turned on ETACS pin 52 gets power, signaling it to turn on the transistor at pin 7(5), point "A", turning the relay on. When the key is turned off the ETACS keeps the relay on for a bit, using an internal timer and the constant power on pin 51. Point "B" is a hard ground for both the auto-down switch and the ETACS, pin 59(57).
I hesitate calling point "A" ground because it is through a transistor and should not be confused with, or used as, a hard ground.
* pins 7 & 59 on cars with the anti-theft system, pins 5 & 57 on cars without.

So pretty much what RealDon said, with a few of the missing pin numbers... :sneaky:

You’re correct… I too should have said that better, like control leg maybe. This goes to show that three minds are better than one…… I only wish I had a whole one.:(...... :)

Edit: changed wording to control leg, I like that even better.

OK so I am off work today and I have the panels off of the car doors and I’m looking at them now apparently the motor on the driver side was never plugged back in and that fixed that issue. The passenger side is not working however when I started unplugging and plugging back in the door jam connector now my powered locks are acting up again. Sometimes they want to lock and then unlock immediately other times they won’t work at all. Since I half the time what should we be checking

Unlocking and re-locking has been discussed in the past. The rubber "bumper" in the lock mechanism wears out and causes just what you experienced.
The locks not working at all and the passenger window still not working still appeared to be tied to the wiring in the passenger door.
OR (in the case of the passenger window) have you accidentally depressed the window lock button on the drivers door (common mistake)?

And I have not done anything else but now the powered locks seem to be working fine. My car is just an electrical nightmare

With door open try moving wire bundle around in between door jam and door to see if it affects operation of door components. If it does you still have wires broken in bundle at key movement point when door is opened or closed. Or still a problem with latch connector at door.

No it does not affect it
OK… If you still have door panel off and have a volt meter, turn key on and check for power at window switch at pin 9 with Blue wire and black stripe.

If you have power there check for power at pin 8 Green wire with yellow stripe when pushing window switch to down position.

If you have power there check for power at pin 3 Green wire with black stripe, also when pressing window switch to down position.

Let us know what you get.

I think it is the doorjam connector because if I touch the connector it messes with the locks so how would I go about fixing that. My friend would like it fixed before we Goto Florida so she can put the window down😂
