I have low cooling from my A/c (300CE R12). normally it is low in R12.
When I get the R12 filled, the first few days it is really cool.
Then it starts to get less cooler. My mechanic filled it with air at high pressure and left the car & the A/c running for two hours. no drop in pressure.
He believes the R12 leaks very slowly from the compressor & it would be better to replace the compressor.I would like to know the options.
The temperatures here are 47C now in the summer.
I have noticed that cooling is much beter in the toyota's & the Nissan's here in Dubai.
Will a compressor from these cars fit & will it give a better performance.
Too many questions as it keeps getting hotter.
