HI,

Will it unlock manually with the key?

I also need the last 8 of the vin to pull the schematics

Customer: replied 1 year ago.

there is no key for the trunk .45022778

Expert:  Eric replied 1 year ago.

HI,

Are you sure on the year? I dont show the ES330 starting production until 2004. Before that, it was the ES300. Just want to make sure I am pulling the correct information

Customer: replied 1 year ago.

ok sorry yes its a 2004

Expert:  Eric replied 1 year ago.

HI,

Ok, the switch gets power from the body ECU.

Remove the switch and check for power on the blue with yellow striped wire at pin 2 on the connector. If no power, then either short in the wire between the body ECU and switch or faulty circuit in the ECU.

If power is present, check for power on the red wire at the connector while you have the switch pressed to open. If no power present, replace the switch.

If power is present, we will go from there

Customer: replied 1 year ago.

ok and where is this switch?

Expert:  Eric replied 1 year ago.

HI,

That is the button to open the trunk. It is actually a switch

Customer: replied 1 year ago.

Ill check this tomorrow hopefully. Is there a fuse just for this trunk button?

Expert:  Eric replied 1 year ago.

HI,

No independent fuse. It gets its power from the body control module.
