How do I fix my `95 Toyota Avalon rear defroster/defogger? 95-99 same car. All relays and fuses are okay.?

Question

Okay, so the rear defroster/defogger doesn't work.
It doesn't turn on, the button doesn't light up, and I hear no sounds or anything at all. I haven't been able to find any information online, useful or not. If someone could tell me where the connectors for it are it would be very helpful, because I don't want to remove the ceiling lining not knowing if the line even goes on the roof or if it goes elsewhere. I've looked for books but haven't been able to find it. All fuses are okay, all relays are okay.
Also, my vents don't close although I hear a clicking sound when I push the button and the AC doesn't work although there is freon inside and there is pressure, when you turn on the fans, the AC light turns on as well as if the AC works but it doesn't and cannot be turned off. If this helps in anyway since it's all on the same pannel.
Someone please help.

Thank you in advance.

Thanks "mtbman101" I tried getting a schematic but I couldn't find a book that had it. It's as if this car is so rare that no one has ever heard of it and never wrote any manuals on it.
Thanks again.

Answer 1

Sounds like there is a problem in the actual switch. I would try and get a wiring diagram and test the switch before just buying one as most dealers have a no refund policy on electrical components. Good luck!

Answer 2

The defrost connectors on the glass are hidden behind the panel between the rear dash and the headliner, remove these and check if one of them has come off the glass.
This may explain why the light won't come on and defrost won't work.

"Get the Toyota because of the fact Toyotas are sturdy" ? A Lexus is a Toyota! ok, now that that's stated, i'm going to grant in basic terms a sprint - the Avalon has traditionally been an American-ized automobile - it quite is been referred to as the Toyota Buick. The Lexus ES series has been close to-luxurious -to- game sedan. you're able to opt for to rigidity the two, of direction, yet i think of your determination relies upon on what style of automobile you're finding for.
