MB guru, please help! My C class started drama
since yesterday, I noticed the A.c was not too
cold yesterday, so I took it for gas refiling stuff,
which it began working fine and driving
smoothly, but today when I started the engine
in the morning, the said A.c went back to the
old way of not of not been cold, this evening I
noticed the gear area became very warm also
the AC blowing warm breeze , also my RMP
increased to 4000 rmp when I switch the gear to
"P" but when on "D" - 2000 rmp with AC on.
please help if this is normal and the way out to
that AC and the warm stuff. Thanks

Take it to authorized M/Benz workshop. Very simple.
