Sounds like the system is surely low on freon for whatever reasons (ie:slow leak out, etc).

If a prior shop did all of the A/C work as you said (and most is new and they recharged the system), I'd surely give them a call and ask if they can check things out. I don't know what their warranty period is for the work performed or the parts, but hopefully they would work with you in diagnosing and fixing the issue (if they are reputable and nice folks). Do you recall what the shop fixed and/or replaced?

If you had jumpered the A/C pressure switch and the air blew cold continuously, then it would have been a simple fix such as replacing the A/C switch on the canister. Now that you have jumped it and the air is not blowing cold, my guess is you definitely have a leak down somewhere which let the freon bleed off over time. The compressor should cycle (under normal operation).

Does your A/C switch on the canister look new, or does it look "old" (ie: has possible dirt around it or the connector)? It *could be* possible that the A/C switch is bad as well, like I said, they are prone to failure sometimes - but I'd rather see that your A/C system is checked for leaks before saying to replace the switch too (don't throw parts at it).



If the shop replaced quite a few components, it's quite possible maybe when they reconnected the lines, the lines were not connected 100% (spring clips loose), or maybe the O-rings on the fittings are dryrotted, cracked or misaligned - this too would cause a slow leak over time.
