Hi guys
this is my first post here hope to get some info/help
own a 04 Astra H with Z20LER
There is no cold air from the system for the first 2-3km of driving if i left my car parked overnight or when i drove it after work(8-12 hours of stoppage)

Other than that it is working fine.(once the cold air start coming in, it is working perfectly fine regardless of the number of time i start/stop the engine)

I've send it to agent to check,found no problem/leak. They service (drain, vacuum and recharge the gas) the air con since mine have not been serviced before. But i'm still having this problem

Can anyone tell me what's wrong
