i have a 1990 GL with the normal factory installed AC system.

the last time i used my AC was early last summer, and it worked okay, but
didn't get very cold.  now it seems to not get cold at all.

assuming that it just needs a new shot of freon stuff, how much should i
expect that to cost?  i definitely don't need AC enough to pay big bucks
for any real repairs, but if it's just needs more freon, i might consider
it.

as always, thanks for any advice-
