How do you know if the ac compesser is good or not on 01 s500

After putting r134a in line started car and heard loud noise from ac compressor area. Now I don't have cold air blowing. I thought maybe I put too much refrigerant in the system.but, car started smoking from engine belt and would not start up for the first couple times. Now I can start it just fine but, no cold air.nothing but air in the line now.

Refridgerant should NEVER be added to a system thats not running in on posisition ( says so right on can) , there is a multiude of failures that could come from doing this , belt failure's , hose failures, rec tank opening
evaporator coil openings , pump failures
i suggest getting a professional to look at it to see what dammage was done

remember laws of physics 101: Liquids don't compress but gasses do and it takes very little liquid in a gas system to destroy the parts of system

SOURCE: just replced suspension compressor in 2002 s500 mercedes was nois

TYPICALLY this could be because the air bags are leaking and caused your compressor to overwork itself to death. The airbags are not designed to withstand temperatures below 40 degrees and above 94 degrees. Can you believe that!?!? Dry rot starts forming on the inside fold of the bag making it very difficult to detect with the soapy water test. Anyways.. i went through all these problems and several hundred dollars before I finally decided to convert to a passive coil spring system. I got it from Strutmasters.com with a lifetime warranty. http://www.strutmasters.com/mercedes-s-500-suspension-s/112.htm I have been riding on them for about 8 months now and am very pleased so far! I actually now PREFER the coil spring ride to the air ride and was surprised at just how comfortable the ride was. Hopefully you won't have to go through as much money and heartache as I did before I went for a more permanent solution. By the way, my shop only charged me an hour per wheel to install the kit so it was pretty cheap on labor too!!!!

SOURCE: 2001 Mercedes S500. Air conditioner won't blow cold even though

I think that this might help you. The a/c compressor is a continuos running type there is no clutch. It has a wobble plate internally wich changes the piston stroke. Screw the genises machine-it is probably only reading a partial on the climate control module. see if you can find the self diagnoses diagram either from the factory or if you have all data. you can pull the codes right from the unit itself and they will be accurate. If you can,t pull codes see if you can get an actual value of the sensors in the a/c unit. You should be able to pull that up as well if not try the genisis. Look very closely at you evaporater sensers(left and right) you will probably see a -40 degrees-that is the sensor default input reading when the sensor goes open. That sensor is used to moniter the wobble plate position of the compressor.

SOURCE: ac not working on 2004 s430

If you have the hood up stand outside while someone activates your air off and on and see if the clutch on the compressor goes on and off while they activate the switch. If that isn't it the it could be improperly charged system or your climate control door that opens and closes for hot or air is not working properly and only stays on heat.

2000 jeep cherokee AC compressor clutch makes 2 rattling noises when I first start the engine for the day. It only started doing this after I recharged the AC with r134a because the AC wasn't blowing...


Does it make the noise even if the ac is switched off ? Its possible you have too much freon in the system, but the compressor should not be involved if it is turned off.

I am looking to convert the AC over to 134a. I have heard that the oil, the dryer and the expansive valve need to be replaced and then the system vacuumed out. where are the expansion valve and the dryer...


Look for the expansion valve where two of the AC lines connect together, usually near the radiator and the lines may be slightly different diameters, the larger one contains the valve. It is also VERY important to flush ALL of the old oil out of the system. Do this with an AC flush kit and all parts removed. Concentrate on the condensor and the evaporator after the hoses are flushed. Coat all 'o"rings and seals with AC oil when reassembling and be careful, leaks can happen and will be costly. Install 1/3 of system oil capacity in compressor and TURN the compressor by HAND after hoses are installed to it. OIL DOES NOT COMPRESS!! You may want to have a shop evacuate the system when ready.

Ac makes loud chatter on acceleration been throuhg


hi, there is a published technical service bulletin about this problem for these vehicles and the tahoes. the compressor sitting so low in the system, gets over-run by the liquid freon banging internally and actually locks up on and off during operation. this is the noise you are hearing. apparently there is a screen kit to install in the low side suction line to prevent this from happening, but GM also states the compressor needs to be replaced and the new compressors from GM at least, already have this modification done. So, i replace them when they come into my bay with the complaint you speak of, and the tensioner for the belt, likely the belt too. but it looks like you already know all about that. hope i could help.

I have a 1990 240 DL volvo and there is a loud screeching noise when I turn the A.C. on and turn corners. If I turn the A.C. off the noice stops. What is it, and how do I fix it?


Your drive belt tension may be set too loose or the belt itself is going bad. If you have a spring loaded tensioner, that may have weakened as well. Bottom line is that when belt is not tight enough, the normal load from the compressor added to the extra load on the pump when turning causes the belt to slip (making noise) Eventually, it may begin making noise when started as the alternator demands more power in order to work (you likely have heard cars with this problem in parking lots...loud screech right after starting) Wish I remembered which method they use to restore tension on yours butyou can easily get that info in any inexpensive manual (they may even allow you just to browse it without buying)


Good Luck!!!

Turning on the ac kills my engine


Sounds like the clutch in the ac compressor is bad. Locking up and putting strain on the motor enough to bog it down and kill it.
