    Just had the a.c. fixed 2 weeks ago and it just stopped blowing cold. Any hints what to check first?

    Is the compressor cycling? Hi/low pressure readings, visible leaks under black light, if you force the compressor to engage with direct 12v will it blow cold?

    My guess if it's two weeks past repair you have a slow leak, and the compressor won't engage as a safety measure.

    Several things to check,condenser blocked with bugs,leaves,even a walmart bag.Is compressor cycling? Maybe the full charge of pressure found another old o ring to blow out a small leak.If it was my rig,I would get a $30 can of R22 with stop leak and a built in guage on the charge hose.Then i would see what it shows on guage when or if compressor cycles.If compressor comes on and its low on the gauge(I would top it off.Does it blow cold or cool to say 70° then after 75° it starts to blow warmer? If its indeed a Small leak,the Stop leak will usually get you thru for the summer.Just kind of depends on how much "grip" you are willing to sink into it.JMO

    Agree. If you service for leaking Orings they should've pulled everything apart and replaced them all. The Orings are dirt cheap!!
