I did AC diagnostics using
http://www.eclassbenz.com/acdiag
and found my ac pressure was 3 bar and i have to recharge it.
I bought
Arctic Freeze R134a 18oz can with gauge.
I recharged it and now the reading says 8 bar.
I think thats still low.
the air is blowing little colder but not like 55 or 60. its doing 69-70 i guess.
