[Shotimes] A/C woes

[Jason Hartberger]

Hey gang, I have a perplexing question. I recharged the A/C system in 
the wife's car up to about 45 psi, but the damned thing still won't blow 
cold air. I looked at the clutch, and it's rhythmically cycling on and 
off on MAX A/C. I did the broomstick (actually mop handle in this case) 
test with no different results. It'll turn on for about half a second 
then shut off for about 3. I hooked a pressure gauge up to the low 
pressure port and it was at 45 right before it would cycle, then it'd 
turn on and immediately drop to about 20, at which point it'd shut off. 
then it would slowly get back up to 45 before it'd try again. wtf is up 
with that?

Also, I've noticed a low whistle coming out of the intake at idle. I 
spent like 5 minutes hunting for it 'til I took the air filter off... 
sounds like someone's in there whistling a really low note. It's pretty 
loud. It goes away as soon as I goose the throttle and it comes back as 
the engine dips back to idle. All gears.

Anybody know what's up with either of these symptoms? Any help would be 
greatly appreciated.
