Question about Mercedes-Benz E320

1 Answer

My a/c blows but not cold.

I had a guy hook up gauges today and said I had enough freon. About a week ago there was a rattling noise when I had my a/c turned on and then it stopped blowing cold. My first thought was the compressor, but the guy who checked the freon doesn't think it's the compressor, but maybe a pressure sensor. I am totally confused. Any ideas

First you need to confirm that your compressor is actually working. to do this have someone turn the ac on while you are looking at the motor. You should hear a click and the motor bog down a bit this means the compressor is working ( if this dosnt happen you need a new compressor). After you do this let me know what happens and i can assist you from there. feal free to contact me at for more insight.

GMC Acadia AC not working properly

Not sure if I'm too late to answer this one, but you're describing a low refrigerant condition. The hissing noise and constant cycling of the compressor clutch are indicators of that. You should recover the system, record how much refrigerant was recovered, evacuate the system (with a vacuum pump), add A/C dye, and recharge the system to capacity. Common leak areas on these vehicles include the A/C condenser (located in front of the radiator), and the evaporator (located inside the dash, and requires complete removal of the interior dash to replace it). If you can't find a visible leak after running the recharged system with dye for several weeks and it starts to blow warm again, you will need to use an R-134a leak detector to "sniff" areas of the system for a refrigerant leak.

Just today I was driving on the freeway at 60 miles per hour, then the car started to drop down to 50 mph and rattling noise appeared...slowly got off the lanes and on to the shoulder lane and called road...

well you need to check a few things, first make sure you have enough oil in the car by checking the oil dipstick, if low, add, if good check your coolent fluid level if low, replace. if full check the timeing on the car if you slipped time your car wil rattle bad, or vibrate bad. could be a serious engen problem. but timeing belt is where id start. i hope this helps

The AC on my 93 Buick Park Ave used to blow ice-cold. About a week ago it went out, and so my husband charged it. Yesterday it was out again. We got a freon/stopleak/leakfinder to put in, and the AC...

sorry it has a leak ,only way to fine it is to use the correct machine and vacumn it out ,then turn machine off and listen for a sucking sound ,most likely cause is the flexible hoses/compression fittings or the seal on the front of the AC compressor ,if you still cannot find the leak then fill AC with a special dye and use a ultra violet light and yellow glasses to find the leak .

Not blowing cold air, but has freon

I had this problem before. If you were hearing a rattling noise everytime you ran your air conditioner, and now it is not blowing cool air, that means your compressor is gone, you need another one.
I have a Dodge Stratus and when I would run my air i began to hear this rattling like balls were in there, but not real loud but enough to know that it was noticeable and that is what it was. I hope this helps

My air conditioner is not blowing out cold air. How much freon do I put in a 2000 GMC Sonoma ?

That all depends how much freon it still has in the system, best way to check is with some a/c gauges, if you put to much it will not cool or could damage some thing, and if not enough will not cool right, used a/c gauges for right amount of freon, now if the a/c system is empty it takes 1.88lbs of 134a freon.

My ac does not blow cold in my 97 cadillac deville but it does blow just not cold and its n ot the fuse what can i do?

You probably have leaked out your freon after so much time. Try adding some more Freon if it doesnt stay charged you may have bigger issues.

Loud noise from 99 Honda Accord

is your ac compressor located on the left side as well and also try your ac if its not blowing to cold the rattling could be your ac clutch on the compressor if that is you will have to get a new clutch kit from your local auto parts store to fix it
