GLE 400 AC takes 10 mins when hit out
just bought a 2019 GLE 400. The AC was recharged 2 years ago and 8k mi ago by previous owner. It’s a black car. When it’s 80 deg it takes 10 mins to blow cold air. Tire shop does AC recharges etc and they looked at it and said it was fine. I still wonder. My previous 2018 GLE 350 seemed to cool faster.
can I buy a recharge canister at Auto Zone and try and top off the system? What if it is actually full already? Will I mess something up or will it just not allow refrigerant into the system so I can’t screw it up?
thanks
