how to disable rear defrost
I am afraid of bursting my rear window. Is there an easy way to temporary disable rear defrost (never use it, but accidentally gets turn on when putting thing in cup holders w/o me notice etc). The fuse(#15) in the engine bay for this involve other systems (multiport fuel injection). 2003 V6. Thanks

Remove the interior hatch panel and then unplug the electrical connector on the window and secure it out of the way of any moving parts.

Alternately, break rear window with a bat. Not a problem if there is no glass to explode!

Lol enjoy your weekend!

Seriously though I never use that defrost button at all out of fear. I should unplug it myself.

You can in fact just pull the fuse, it is just the "defog" , pop the hood, open the fuse box just behind the battery. The defog is next to the fuel pump and unrelated... at least on this 2004 v6.
Fuse layout is on backside of the fuse box cover.

Mine has been out for a bit now, tossed it in the glovebox in case i need a spare.

$430 for new glass.

Mine runs just fine without.

Maybe they are different south of the border?

...extra wires (red is not attached) were for an air compressor for the old Rancho9000 shocks.

Same fuses on a 2007. Just to be clear, the indicated thing your pulling is the relay, not the fuse.

I don't believe mine has the mirror defog, so just pulling that relay should be sufficient. When you hit the defog button, you here it click. After removing it, no click.

Started the car, and no CEL, so it's not multiport fuel injection.

Anyone got a picture of the specific plug to unplug in the rear hatch to disable the rear defroster and leave intact the heater mirrors?
