Power windows not working

Pretty sure it's a box and they didn't have those.

Do you have picture of the ground

[sly]

No. I don't have the 88 any more to get that pic either. There may be enough of a difference between 88 and earlier cars that the body contact for the grounds may be in a different spot. I do know that my former 88, 93, 2000 and even my 03 Expedition have ground points where local accessories are grounded in that location, so I'm pretty sure yours should have a ground point to the body there too. I think the 82 Mark VI I had also has a ground point there. Should be about an inch from the door jamb, behind the kick panel, either down near the carpet or about 2/3 the way up to the dash IIRC. Basically look for wire(s) with a ring terminal that's bolted to the body.

Ok I’ll look and my wagon is a 1987 forgot to mention that

[rellik god]

Was under dash tracing grounds and found this connector with plastic cover what’s this for

[sly]

That's a new one on me. Haven't seen that one before.

Does it have connectors for a tripminder?

[rellik god]

I don’t know i did unhook all Cruise control stuff

[friskyfrankie]

Would be interesting to track all the wires coming and going into that connector to see where they came from and where they are going. I do seem to remember a connector similar to that having wires/s for a part of the tripminder harness. But then, I'm old so there is that!

[Tiggie]

Tripminder harness has those funky clear covers in that location for certain years.

Got driver’s window working took all related connectors apart and sanded contacts.while I was doing so I came across one relay I couldn’t identify the brown connector relay any one know it’s on passenger side

[sly]

The brown one is probably the autolamp relay. Check for a soldered wire on that metal hanger. DO NOT REMOVE THE HANGER FROM THE RELAY if it is soldered to a wire. That will break the relay. That's the ground for the coil. These are completely unobtanium. They are dual pole dual throw and technically 6 pin relays.

If it doesn't have the wire soldered to the clip, then I've got no clue what it is for. But I'm pretty sure that's the autolamp relay.

[rellik god]

I don’t have that auto light option on my car could’ve it been just installed just in case an ad on auto lamp

[sly]

Check the relay for that soldered wire. If it doesn't have it, it's not the autolamp relay. That's the ONLY "6-pin" relay in the car. The rest are the usual 4/5 pin relays. If it doesn't have the wire out the back soldered to the clip, then I dunno what it's for.
