Hopefully that’s all it was. Generally though, if an AC system is low and it is not from what you are describing as a possibility from the factory, then there is a leak.Well in my 2020 I had it checked for the AC issue yesterday...and it was undercharged. So a replace and refill/top up was done and BOOM much colder than before. Been reading some trucks are coming undercharged?
Did you ever get an answer on this? I'd love to see a picture myself. I have clamped off both the hoses going to the upper portion of the firewall but haven't noticed much difference, blowing about 51* at 100* ambientWhere is the install location for muzzys A/C hack on the 3rd gen ecodiesel. Pictures welcome please. TIA
