You might mention, when recommending this stuff, that's it illegal in his
locale and no professional shop will touch his system with it in it.
Anyway, (to the OP), if you're going to be servicing your A/C system you
would do well to clean all the electrical connections under the driver's
side 'D' pillar as preventive maintenance; a lot of people have reported
damage due to corrosion/poor connections, etc.

I used some stuff called Maxi-Frig. Direct drop in. Not supposed to put a
vacuum on the system, just load it in.

Works great! Well I mean for a van. Cold air at least, very cold.

Held for about a year now.

YMMV
