I agree with Curly. R-134a systems are even less forgiving of blind
additions of refrigerant than the old R-12 systems were. At least on those
you often had a sight glass, and failing that a set of guages gave you all
the info you needed to get in the ballpark. Not taking in the refrigerant
makes me think the compressor isn't engaging... which is in itself a symptom
of all sorts of A/C possible problems.

Count your blessings that it didn't take on more charge. If your charge was
very low (especially in a car that is only 10 years old) you have a leak
that needs to be repaired before your A/C will give you decent service.

Anyway, I've learned my lesson. In the days of R-12 I'd do it all myself,
but R-134a is just too spooky for my talents. I will do the troubleshooting
to determine if the problem points to the "charge" (the amount of
refrigerant) and if that's where the problem is I take it to a pro. It's
cheaper in the long run. An A/C professional will be able to find the
problem very quickly even if it isn't the charge, but when I have more time
than money I at least like to hunt down the device responsible for the A/C
not working.
