1994 Chevy Silverado

[Gnatty]

Hey guys I have to be honest I really no nothing about Mechanics, so I'm just asking on here.
Okay, the issue I'm having is the A/C. When I got the truck the A/C was completely freezing. Recently however, the compressor was having issues not engaging and I fixed that by simply plugging the cord to the accumulator thing. . Now the compressor engages, but is not cooling really at all. It is an old truck and the compressor is a little worn from what I see maybe 2mm space when not engaged. I checked the levels of freon/coolant with a gauge and the amount is perfectly fine. Plus there seems to be no leaks. Just wondering if anyone has any ideas?

Thanks

bring to an auto ac service shop. this may just need the clutch gap adjusted. have them check the pressures .

1994 I believe uses / used R12. with R134 and the conversion oil installed the system would need be cleaned and the oil replaced for the compressor to survive if this was converted to r134.

by shorting out the low pressure switch that is not good. could be a bad switch . could also be low charge.
