AC Question

[Toddfromtexas]

Recently purchased a 94' 3660, air blows but not cooling. Cleaned coils, Compressor is kicking in and cycles when temp. is adjusted.
I am looking to check freon levels, but only finding 1 fitting on the back side of the Sanden compressor. Should there be 2 a high and low side if so where an I missing the other fitting.
Thanks

I haven't seen a system that did not have both fittings for your gauges. Normally, the high side pressure line should be the smaller line going to the compressor and the suction (low pressure) side should be the larger line. Try tracing those lines backwards from the compressor and see if you don't find a separate fitting in each line somewhere in the plumbing. Not so easy to find in some set-ups...
