On my w126, as some of you know, now has ac working. And just like everyone says, I am dissapointed in r134 cooling ability. I need to figure out how to get every bit of cold air out of the system! So I would like to know where the outside air intake is located.

I took out the glovebox, and it appears the big flap right behind is what I am looking for. Can I push that all the way open to prevent hot outside air from being sucked into the ac system?

Another sort of off topic question - when my ac is going and I am in rush hour, sometimes my engine temps get up to 90 to 95 degrees C. Is this a cooling problem or is this normal when AC is on and stuck in rush hour?

Thanks!!!
