Hi, I own a 91 Mazda 323 saloon car. I would appreciate if anyone could
provide me with some info on how to rectify my cars ac.

The ac compressor was working fine but making a minor internal noise,
thats when I decided to get it recover and recharge the ac gas with
lubricant oil. Also had the evaporator removed and cleaned. The garage
guys had recharged the ac gas with R134a while mine was a R`12. I
wonder how they managed to do it cause the pipes have different types
of adapters.

The ac was cooling fine infact very good but the ac compressor noise
was really loud now making quite a racket. The noise comes only during
idle or while slowing down, it stops once the car is moving faster.

After nearly two months the ac has stopped cooling. The ac compressor
works fine but there is no cooling at all. Also I dont hear the hissing
noise of the expansion while which I used to earlier. I have a feeling
that the entire system is clogged due to mismatch of ac gas and oil.

I have also checked the system for leak- none and the condensor fan and
radiator fan is working fine.

Could some one suggest a cost effective remedy?Cant afford to replace
the entire system..
I m pissed at the garage guys who didnt flush the system before going
in for R134 gas.

Please help!!!
