Do power mirrors work?If yes do you have antenna that goes up when radio is on> if yes rear defogger is powered by module on right side trunk. Should have 12v black/blue wire

Power mirrors work, no power antenna.
I've looked in the trunk and couldn't find any type of relay on the right or left side.
Once before I had the rear seat out, it appeared the grid wire went under the carpet toward the front of the car.
It was hard to see, it was taped/wrapped up to other wrapped wires that did lead into the trunk
Up to that point the grid wire was black and white.
Guess I could pull the seats out again and look again.
BTW not sure if it matters but the Chrysler intrepid is a Canadian model

You won't have relay no power antenna. Power comes from switch to right side of grid by black/white wire. Comes along right door seals up behind seat then into head liner to widow. Connector should be at seat. Also ground on left rear fender

Yeah I just took the seats out and looked in the trunk. Nada
Passenger side of grid is grounded to the body behind a panel.
Driver side is a connector with a black/wht stripe wire that goes behind the rear seat, under the carpet/door sills up to the driver side kick panel, from there I have no idea where to look.
Is the BCM connected to this?
Maybe the ac control/relay is powered backwards?

BCM not part of wiring just switch timer wire to window and ground. Try checking at switch for power.

Pretty sure the switch works, lights up and the relay clicks.
I think the relay is relaying NEG power, I'm not sure if there is anything between the AC wiring and the defrost wire.
Thanks for the help BTW,
I'll pull the ac control out again and check a few things.
I think the relay is currently setup like this
Df wire or something else
Pos Neg < - 2 white connectors on side
Neg - not sure what powers this connection, was showing continuity on 3rd top pin from big blue ac connector.
There are also 3 wires going to the relay block area, one light blue connector I didnt check and 2 white connectors, constant POS and defrost button NEG.

On the relay that click when you push button do you see a black/pink wire? If yes voltage on it.

From what I can tell
The two white connectors to the block of the relay control the relay.
Ones always positive, the other is NEG to the switch
_ to blk/w
| - To Blk/r?
The other 2 relay terminals seem to connect to wires on the black connector of the Ac unit.
One to a black/white stripe wire
one to a black / red stripe wire
The black/ red stripe has a 12v NEG when the switch is on, unless the fan switch is on too. Then it drops to 5v as does the black/ white wire.
The black /white terminal has 12v NEG, when the switch is on.
I pulled all the wires on the AC, and disconnected the driver side grid wire, there is still a ground.
With the wires pulled on the AC unit the black/white wire in the connector is also ground.
And the relay sends ground.
I'm lost lol.

So far I've traced the grounded ac/grid wire to the fuse panel.
Top middle connector on the back side
Its a light blue/ light green stripe wire. Any idea where this wire goes?

Do you have auto A/C?
Can have your Email I'll send diagram of defogger circuit.
