Hey guys so I have a 1986 Buick Regal and my AC & heater doesn't work. I saw some videos on YouTube on how to recharge a car where the AC doesn't work but most of them were newer cars. Is it the same for G-Bodies aswell where I can just get a refrigerant can that they sell at any auto parts store and connect it to port or no? My heater also doesn't work and I wanted to ask you guys if you guys know how to fix AC & heater on g-bodies. I tried looking stuff up on YouTube but all that comes up is AC delete stuff and whatnot. Thank you guys for taking time to read my post & maybe help me out! Much appreciated !
