Question about cooling guys.....AC
Bout the only problem I have with my car is the AC. I have factory window tint which is pretty scant so maybe that is my problem, but it just seems like my car AC is constantly blowing like a jet engine. Yesterday it was running around 90 and bone dry as usual here and the friggin AC just cranked non stop.
My kids were whining in the back and even my wife was like, "wow, you would like Mercedes had better AC than this"
Only way we could get it to cool down was to run it on MAX LO on all sections for about 20 mins....then we set it to around 72 and it relaxed to about 1/2 to 3/4 bars, but never went lower.
Should I take the car in to have it checked out....or is the E AC a little rough.
You guys in the hot climates ever have the AC system just do down to low and maintain? Our SUV AC is much better. You hammer it to get the initial cool down, then put her on low to maintain.
Thanks as always for the input.

I am not sure how hot it gets where you are, but we had quite a few days up here where the temperature shot up past 39deg C.. (102F +)
On my car, I have NEVER set the air conditioning fan speed higher than the half-way mark.
My car is black on black so you know how hot it gets inside my car when it is parked in the sun. Once I get moving on the highway it super cools (5 or 10min and I am comfortable).. On the street it takes approx 15 - 20min to get the inside temperature down to where I want it..
FYI.. I set my Air con temp to 20C when it is really hot outside and then have to turn the fan down to 1/4 speed otherwise it gets too cold inside the car.
Short answer is: get your air con checked because I think it should work a little better than that.

Thanks so much V....I was noticing your windows are suuuppper dark. Did you notice a huge difference when you blacked them out.
I can't run that dark here....cops are REALLY strict on tinting...I can go a little darker than stock, but too much and they pull you over and check the level of tint.....life in **** Mormon Germany.

Jim,
Aftermarket tint makes a world of difference. I have a 30% tint on my E55 and it is amazing the difference this summer compared to last summer.
I'm guessing Victor has the same experience since his windows are tinted. Although, I don't remember my car running constantly last summer before I had tint. The back does not cool down nearly as fast as the front. The vents in the center console are lame and the vents on the b-frames are even worse so the rear seats don't get much air in our cars. Bottom line...you need tint.
Cheers,
Darren

But, I can tell you that when I get in the car after it has been sitting in the sun, the leather is so hot, you would burn your legs if you were wearing shorts.

Jak,
The legal tint limits for Utah are shown in the following link. The numbers denote % light transmission:
http://www.autowindowtintings.com///...=tintLaws_Utah
If you're not familiar with the available tinting films, make sure the film you select is reflective (aka: metalized). The non-reflective films are merely dyed films that will eventually discolor and bubble.
My ex-inlaws used to live in Tooele, so I know what you're experienceing.

It should work much better than that! I use my AC in 110+ degree temps daily. I do have 22% tint. Black car.
I usually freeze and have the Auto mode and temp set on 78. I usually see the fan on speed 1,2, or 3.
I admit if the car has been sitting in a hot parking lot for a long time, it is a little weak. Not how much it cools, just how fast the highest fan speed is... it seems a little weak. But that only lasts for the first 5 minutes then all is good.
Your dealer's answer is stupid. Something is wrong, get it checked.

Thanks so much everyone...time to go argue with the dealer when I should be getting my a$$ kissed like I hear at Lexus.....grrrrr!!!
I mean seriously...that is a little harsh, but all I really wanted when I called was, "Wow, should be working better than that, why don't you shoot it by and we'll take a peak at it" Instead...more excuses and silly responses. Benz is just lost on customer service aren't they.

This is wierd. I find the AC in my E55 to be one of the best I've had. My car is Techtite with black interior and the temperatures were constantly in the 90s-100s this whole summer. I do have 30% tint, however. What I'm wondering is if you are complaining about the noise or the effectiveness of the cooling.

Both.....It runs at high speed constantly.......it does get the car down to around 70-75 degrees...but never goes below half speed and mostly is about 3/4 speed.
So yes, when it's cranking non stop...noise is an issue as well.
Most be an AC problem...it just has to be.
Just not right.

You can hang meat in our E500 it gets so damn cold. 110 in Palm Springs is not a problem for this stock Techtite/Black car. Sounds like you need to

Hey last question.
Above the digital screen with the temps...there are the 2 vents and in between is a dial that has blue lines on it. I read in the manual that the dial controls the amount of cold air allowed into the vehicle. Any idea if which direction is "letting the most cold air in". Is it when the blue lines are being shown or when they are not.....any ideas. Maybe easier to explain, when I roll the dial up toward the hood or all the way down toward the shifter.....who knows, maybe that has been my problem all along.

I didn't see this mentioned, but maybe because it's so simple it goes without saying... but what I do when I hop into the car on a hot day is to lower all the windows and open up the pano sunroof and let all the hot air escape. Drive around for a bit to force the air to circulate since when the car is parked the interior temperature gets higher than ambient. Then, roll up the windows and blast the AC and it doesn't have to work as hard.

Is it something that 2005MY models don't have?
It has a dial on either side of the vents with white lines.
