Lightbulb 99 F 550 7.3 Ac dont work at low rpm

My ac stops working when i am stoped or at low rpms, if i rev up the motor the ac will kick in and blow ice cold for a while. When i am going at high way speeds it will work great. i hooked up my gauges and they were at 60 on the low and 300 high the motor was at a idle. any ideals.

You should check the air gap on the compressor clutch, low engine RPM is usualy when that showes up.
