[R129 SL] SL-500 Air conditioning

[Jan Kuylaars]

Hello peter, BC, no I was eating New Zealand apples and they were delicious.
But I had a infection in my teeth, and gone two times to the dent ace.
I had a lot of pain, and take some painkillers and go early to bed.
Now he made a hole in the teeth so the infection came out and the pain
disappears.
Tuesday he will fix the hole.

It is not easy to think when your head feels like it is under the back wheel
of a R129

Regards  Jan. FL D

  Hi Fernando,

  I am not too good at translating Italian but it seems like the following
is a rough translation (I use Alta Vista) - Babel fish translator!

  In order to resolve eil your problem it tries to put between the two you
spin of the temperature sensor a resistance, therefore that the same sensor
feels the motrore warmer than those that is in truth-in order to finding eil
just value must take a variable potentiometer  to put it between the two
coils of the temperature sensor that ago partirte the impellers and when the
impellers stess epartono to 85° measuring the resistance value, My 1991SL as
an example were of 700 ohm have put a 680 restitenza of ohm to 1% and now
the impellers leave to 85° also and the instrument nell dashboard marks 90°
and the water more not bubbles.  Hope this sort of helps!!!
  Good to see 'Jan' back in the comments section.  Were you on holiday Jan?.
  Regards, Peter S (alias Benzcruiser) New Zealand.

    per risolver eil tuo problema prova a mettere tra i due fili del sensore
di temperatura una resistenza, così che il sensore stesso sente il motrore
più caldo di quel che è in realtà-
    per trovar eil giusto valore devi prendere un potenziometro variabile
metterlo tra i due fili del sensore di temperatura che fa partirte le
ventole e quando le ventole stess epartono a 85°  misurare il valore di
resistenza,  nela mia sl del 91 per esempio era di 700 ohm. ho messo una
restitenza  di 680 ohm all'1% e adesso le ventole partono a 85° anche e lo
strumento nell cruscotto segna 90°  e l'acqua non bolle più

      I filled up my AC with freon refrigerant and the dealer told me that
the heat sensor for the two big air fans was defective.
      So when I was waiting for the traffic light the cooling from  the
refrigerant was insufficient and then the pressure protective valve should
blow the refrigerant out of the system. After replacing the sensor they
filled up the system for the second time together with a colored fluid.
      I paid for the second time and after two months it sopped working
again.
      After checking hey told me that the colored fluid had leaking out of
the indoor unit.
      To repair cost about 1300 euros. Say 1600 $.
      I am now thinking what to do, do it myself with 15 ours labor and
buying a used unit, or open the soft top.

      Greetings

      Jan.

        Oh My Gosh you just named every problem I am experiancing with my 91
SL500....I thought that I just had a Lemon... I spent 3000.00 dollars to the
Benz dealer for Air Conditioning repair and was sent off to the Middle east.
When I returned 18 months later the Air wasn't working and Mercedes Benez
wouldn't honor the previous work...I am so sad and frustrated.  It blows
cool air for a while then hot....My mechanic can not find a leak in the
system...Any one has any suggestions???
