AC ONLY BLOWS COLD WHEN PRESSING ON GAS. ANY ANWERS?

2005 Saturn Vue • 81,000 miles

AC works only when driving and rpm's are above 1 1/2. Obviously more noticible on hotter days. Takes awile to cool down car if out in sun.
Also noticed a rattling noise. Don't know if it is related. Noise started about a month ago. AC problem started lastsummer.

You have to check the high and low pressures?Also does the ac compressor keep cycling?
