[DML] Re: YET another a/c thread!

Your high side head pressure is way too high. Some of the possible
causes are:
air in the system
a restriction between the high side and the low side (a plugged
orifice, a clogged accumulator, etc)
not enough airflow over the condensor coil (a fan not working, a fan
loose on a shaft, leaves and dirt plugging up the coil)
too much refrigerent
When you figure out the problem your low side will go up higher so you
will have to remove some refigerent. The system MUST cycle. The fact
that is does not again says there is too much refrigerent in the
system and the low side pressures are too high. Also check the
evaporator coil for blockages on the air side. To do that you have to
pull the blower motor.
 To check that the A/C works you read the temp differential across the
evap coil. You look for a 20 degree drop so if the air entering the
coil is 80 the air comming out the vents should be around 60. Get a
pencil temp gauge and check it. Do not continue running with the head
pressure that high. You can blow the valves in the compressor or a hose.

vacuumed and checked fine (no leaks).  The temp today in Mobile, Al 
was roughly 85 degrees and at idle, the gauges were reading 40 and
235.  However, at
