I'm too short to attach the hose thingy to the other thingy on the car, without having to climb up on the running engine and possibly roasting something sensitive or getting caught. But I did google the recharging thingy and showed my wife where to put that hose thingy. Well...I showed her the picture of it and she found it.
This made me laugh. I have a vacuum pump that I use to evacuate AC systems, so I can rebuild the compressor or replace a condenser or coil if I need to. I got the AC working on my old Mercedes, but I have to tear into the BMW one of these days. I think the seals on the compressor are shot. It's the kind of thing that would cost a fortune (and I wouldn't pay to have done) at a shop, but it only costs a few dollars in parts to do it yourself. Well, a few dollars in parts, a bit of blood and skin from knuckles, a couple quarts of sweat, a few hours of study to hone up your repertoire of cuss words (just so you don't have to repeat yourself), and time. But I enjoy it, and knuckles heal.
