Chevrolet Repair: 1994 chev astro van- no heat / ac ,heater core out?, astro van, vacuum line

Question
my 1994 chev astro van has not heat/ac
every so often it would just start to blow,
but not any more.
it also stopped cooling before it stopped working

Answer
Please ELABORATE in MORE detail on what the heat and A/C are not doing and also,

What mechanical work or ANY kind of work has been performed on the vehicle recently ?. As most problems that occur after a recent repair was made can be traced back to the area of where the repair was made as a vacuum line may have been knocked loose or a wire connection came loose, Look around in the area where work was performed.
