If you have a leak, just make a cheap hose like I did. I put 40 psi into the AC system and sprayed simple green to look for leaks.

Beats chasing freon. Once you think the leaks are fixed, put a vacuum on it and recharge.
Today I cleaned and reinstalled the door panels. Years ago when I decided to use the pressure washer to clean the door panels on my flipper dually (same truck I made that hose for), I lamented how much cleaner they came out than the panels on this truck. Today that changed. This was the nastier of the 2 as is to be expected. It really wasn't terrible, but it was grimy from my forearm. Here's how it came out.

The bottom was also kinda nasty where my foot would rest against it. I just dumped a bucket of laundry soap water on it, raked it with a bristle brush, and pressure washed the nasty away. Here's another shot trying to capture how, from the outside in, the windows really match up nicely.

At this point I'd given it a bath too. Also got the mirror blinkers wired up and vacuumed the driver's side and wiped down the interior. I wish I did this more often, even with the hail damage this old truck still cleans up nice.
