Bill does latch the lid, see the statement at the bottom of this post, I
did not snip it out. Hence my statement that the lid is misadjusted.

The lid does need to close to get air to flow through the condenser. Not
enough air flow = high head pressure. No way can you get an accurate fill
using gauges doing this. The pressure/temperature relationship will be off.
Now, if you fill by weight, then at least the fill will be correct, but the
high side will be too high pressure and a hose can rupture or blow off.
Seen it too many times. There is a reason the shop manual has the
instruction to remove the back up light.

You need as much air through the condenser as you can possibly get for
servicing. Certainly not less air flow than the car can produce while
driving it. Remember even the front engine /rear drive cars have pictures
in the shop manual of floor fans blowing air into the condenser/radiator
area to get better readings. Simulates the wind affect from driving the car.

Frank, I don't think there is anything wrong with Bills car. I read it as
he ran the hoses over the weatherstrip and then just lowered the hood onto
them. He did not close/latch the hood. I suspect by doing this he'll be OK
so long as he does not allow high side pressure into his small can of
refrigerant. Of course if someone REALLY wants their A/C to operate
properly, they should make sure all the fins are clean and clear (not bent)
on the condensor and evaporator, (probably) replace the receiver drier,
make sure the hoses and connections are tight (no leaks), make sure there
are no restrictions on the internal flow, and finally use the proper
refrigerant (in our case that is R12) and the proper amount of charge. All
this after putting the system into a good long vacuum of about an hour on a
dry day. Doing all this and using a good compressor will pretty much
guaranty the best cooling available from this system which is a pretty good
system. Especially based on the size of our cars interiors.
