AC Problems
So in the last 2 months my AC as stopped working completely, no cold-hot air neither blower.
The lights are working still.
When i turn the speed dial i can hear the flaps open.
Refrigerant liquid is at around 4 bar
Have heard around that AC can not be working due to low pressure on the refrigerant.
I tried to fill the refrigerant level with those cans you can buy online, but honestly i dont know if i did it correctly.
Connected an car diagnosis tool, it gave the fault error 9040 and when i enter the error it says:
4272 WP369 (sensor ponto de orvalho) (sorry for the error not being in english my tool is in portuguese and i couldnt find the exact translation) dont know if it is the air con sensor or the outside air sensor?
CAR: W169 A150 2005 Petrol
Would apreciate any possible help.
Thank you.
Best Regards,
