I have an 88 cadillac deville, 4.5L. Tried converting the R-12 to
R-134a. I got some freon into the system, however it is not cooling
down significantly. I have the same problem for a 91 Honda CRX. I
did the following for both cars. While car was running evacuated what
remained of the R-12, within a few seconds. Then reversed the
procedure and recharged the system, with the ac running on high. For
some unknown reason it only takes less than 12oz [5psi]? Any
suggestions will be helpful. Why will it not take anymore or get
colder.
