I don't know if im the only one with this issue, but my back window is always fogged up if the temp gets even a little cold, its completely fogged no other windows on the car do and no other cars in the parking lot, even ones that have been there since i park mine are fogged up. Just wondering and yes i after this happened a few times i cleaned my window and it made no difference

Check for water in the trunk! or damp carpet. My old 98 Talon use to do the same as temp get colder because rear gutter where not draining water properly!
And no! my rear window is not always fog in my Koup, but on rainny days I do have to keep ventillation on windows vent!

I agree with Matemorh, there must be some water coming from the inside. I do not have that problem with mine.

Where I live it is very cold, 8 months of the year. I have no issues with my rear window fogging up, it is consistantly freezing up due to the obsurd temperature. Now I do have a concern with the front windshield, it seems it consistantly fogs up even sometimes with the front/feet option. Kind of odd. Also the auto function, still fogs up.. it is irritating.

Most new houses have issues with foggy windows...because everything is so insulated, the wetness is trapped inside.
Connection to cars here?

Dunno, maybe air it out a bit, check for water?

Good thinking ReKoup! lots of snow where I am from perhaps the melting snow from my boots is the problem. Seems logical to me.

no I'm not getting that either. do you have tint? if they apply tinting incorrectly(covering your rear window defroster wires) it can sometimes cause problems. maybe you could try one of the anti fog chems, though I haven't heard great things about them and I've never tried any.

I have the same problem deltron. I feel like I have to have the rear defroster on constantly. I'm always adjusting the heat in my Koup. It's either too hot or too cold or it fogs up, I can't seem to keep an even temperature in it.

The manual says that this can and will happen if the recirc is left on too long.

Good catch Kenny C! OP are you using recirc air? It is well known that you should use outside air if you have high humidity (moisture) in the air.
