Not really if you want the system to cool to its capacity. Moisture will creep in and you still need a vacuum to get the charge correct. The plugs may save the expansion valve and with only 2 weeks down it may be ok. Worth the try on the expansion valve IMHO.

The car is a '91? If so, unless it's been retrofitted, it's an R12 system. Unless Canada is wholly different, where are you going to get R12? Convert to R134? I suppose; I did it on the RSA and it works as well as can be expected. But probably the best thing to do going forward is to let an experienced A/C guy fix you up properly.

It has already been converted to 134a, I will take it to a shop that has all the tools and know how.
Thanks for the help.
P.S. Ken, I see we share the same racing #

Do not jumper around the low pressure switch. Without a vacuum pulled you will never get enough freon in it to cool anyway and you risk the compressor in the process. 134 systems are very finicky on amount of refrigerant and the pressures. Small changes affect cooling temp a lot. And without a new dryer the system is going to get corroded too.
