I come from the Jeep world where if it sucks, and it often does, we throw money and time at the problem ourselves. My sound is bad, put in new speakers. Axles break...buy better ones. So one of the big Grenadier problems is our AC system, does anyone know how to fix this? I have never dealt with a full AC system so maybe it can't be done, but I wanted to ask if anyone here knows. Can we change out a bunch of parts and fix this ourselves? (I know we shouldn't have to, but we are well past that. Let's just enjoy what does work and fix the rest.)
