All cars model from 2000 upwards A/C are controlled by the ECU.

HINT.
Refering to the DTC code.when ever you see DTC 21 on your screen,it means B1421.
When there is no problems,DTC 00 will display.

My AC was out of gas I filled it a month ago in leas than 2 weeks the AC stopped cooling I went to the AC guy who filled the gas and complained he said their might be leakage but when he used something to check if the gas was still in their... There was plenty gas... He was surprised cos since there is that kind reasonable amount of gas that means the thing ain't leaking... He removed all the gas and brought another time of gas ...( canned gas not the cylinder) saying maybe the car does select gases .. He used a new type of gas... He said if the new gas disappoints I will have to change the condenser or that the condenser seal might need to be changed .. Help me sir

How did he know if there is enough gas,does he makes use of manifold guage, because normally there's always a reading for every fault.if not all the jobs he's doing is try by error.

Pls beware car doesn't select gas, except if you aren't using R134A or R1234yf for recent cars.
Meanwhile some gas are writing R 134a but they aren't pure R 134a they are missed gas with R22 and R12 but that doesn't stop your car from chilling but you are endangering the life of your air conditioning system.
Make sure your technician uses manifold guage then I can help you solve the problem.

There was enough gas when he used something to puncture it enough gases emitted from dia... He didn't use any gauge... Well I suspected maybe he didn't use original R134 ....
