OK, once every spring I like to amuse myself by thinking I can get the A/C
fixed.

I want to throw some dye in there.  I can never remember which is the low
and high sides. Is the low side the right hose or the left hose if I am
staring at it from the back of the van.  I have the standard aftermarket
unit from '83 on a WC engine.

Thanks,
Bryan
