Air Conditioning problems
2001 E320
I am in a hot climate (Texas) where the A/C does not cool the interior very quickly. Is there any way to maximize the effectiveness of the A/C or to enhance its performance?
When I set the A/C to blow out of the windshield and/or floor vents there is lots of "leakage" through the panel vents as well. Does anyone else experience this problem?
Is there any way to set the A/C so that the air blows out of the panel vents only (not the floor vents or windshield vents)?
Thank you.

I am so jealous of your problem! I can only dream of the day when I can use my A/C again!
Anyway, make sure you keep the sunroof shade pulled shut to keep the sun out. Then, if you press the recirculator, you should get the coldest air possible. In my opinion, the auto fan settings cool (and heat) the car very well.
Stay cool...

Keep the temp at the lowest setting. Hit the Auto button. Then hit the Recirculate button. If your still having problems with the A/C not cooling fast enough or it is too weak, have the dealer check it out. My blower has been replaced once already for being too weak.

Also make sure the refrigerant is up to the right level.
Best way to check effeciency I found is to stick an accurate thermometer into one of the dash vents, put on recirc, max cooling. After running the engine and ac for 10 minutes the thermometer should read 54-57 F on an 75-80 F day. Just for info, a GM or Toyota will read mid to high forties. They are stronger.
Because I have a evaporator leak, I have to add a container of R22 every 4 months. I can tell when the AC effeciency goes down by the slow cooling.

Hi Peeyoo.......also in hot climate (Natal South Africa) .....E220 Sportline.
Follow other advice ....recirculate etc......but also keep the AC sensor in roof lamp cluster (behind small grill) free from dust / fluff etc....this greatly speeds up reaction to dial setting changes.
Good luck .....Tyke

FWIW, It seems to me that recirculate should not be used until the interior car temperature is close to the outside temperature. For example, car interior temperatures can be well over 100 while exterior temperature is around 80. The AC should provide colder air at first by using air from outside versus the much warmer interior air.
