interior of windows of 94 camry all oily

[alxlai31]

my mom has a 94 LE v6 Camry sedan.
The inside of the windows are all oily.
I got a napkin and wiped it off and its really dirty and black.
I figure I need to change the air filter or cabin filter for her.
is this correct?
Can any one help me please?
Thank you in advance!

There is no cabin filter in these cars. The air filter is for the intake. Having said all these things, I don't understand any defects of the car.

Does she or any other driver of the vehicle smoke?

has the car ever been cleaned?

Not saying this is your issue, but my wife's Camry's windows fog a lot. When I clean them they don't. She whines about it, but the culprit is her coffee addiction. That aroma she smells is more than just water vapor from the cup, it contains oils and other stuff.

BTW, cigarette smoking leaves a brown sticky film.

The fact that its on ALL the windows indicates its not some obscure oil leak from the dash since motor oil won't stay atomized that far, but it could be antifreeze. A seeping heater core will deposit a slimy coating on the inside of the windshield through the defroster. Usually, this is clear and there is a distinct radiator smell when it does it. It also does not usually make it to the rear of the car, but it is very slimy and hard to clean. Antifreeze, as any nail biter mechanic knows, has a distinctive taste to humans, even in very small quantities. It IS poison, so don't do it, I'm just sayin'.

Maybe you have 2 kinds of contaminant, 1 black and 1 oily?

food for thought anyway.

I find that evaporating armor-all leaves a residue on my windsheild. But since you have this issue on all the windows that probably doesn't apply here. Just want to throw that out there as a slim possibility.
