Hi all,
My friend has a W124 with no A/C. I pressed the schrader valve and
there is still some pressure in the system, so it's not empty. I
shorted the low pressure switch and the compressor runs, and there are
bubbles (or something) visible in the sight glass. I did not have my
manifold gauges with me to test pressures. I assume the system is low
on R-12 at the moment. I hate to feed it precious R-12 just to have it
leak out. I don't have a vacuum pump, so I really don't want to open
the system. Is there anything I can feed in that will be compatible
with R-12 (and cheap1), or am I stuck either taking the gamble (add
R-12) or having to discharge, vacuum, and re-fill with a mineral-oil
compatible replacement like Duracool, AutoFrost, or good 'ol R-12?
He's on a tight (read: zero) budget but sure would like some cool air
if possible. Suggestions welcome...
:-)
If you come up with a good solution let me know too. I have the same
problems (and only three precious cans of R-12).
