dear sir
my problem with the car is that i have never switch on the air condition for 3 weeks, then when i start it it give me warm air, we check the gas and it seems that the gas is good but the pressure is not well, we pick out the cup of gas and clean it and also we clean the part of the compressor that on the bottom, but still the air not cold, i think that the gas type was not the same as original, so please how can i fix this issue and what is the type of gas for the epica LT 2006??
