New problem with the A/C just started an hour ago.

       Drove home for lunch, A/C worked fine.  Got back into car to come back
to work.  No A/C  hit the AUTO button, nothing.  I hit the Snowflake button,
I can see the snowflake quickly light up, then goes off.  I can't hear the
clutch engage.  I cycle through to see what errors are being reported.  I get
15.1 and 29.2.  I tried to find the page that gives me the diagnosis of what
these mean from SMJ Auto-Technik, but I can't find the page anymore.  Can
someone send me the link or tell me what those two errors are?  I am guessing
one is the faulty heater valve that I will be replacing soon, but I have
known about this one for a couple months.

I am hoping that by shutting the car off for a few hours it will somehow
reset itself.  Stranger things have happened.  Any ideas or been there's?
