Head pressure can be bad at these hot temps, making cycling of the compressor even slower. If head pressures are high, the compressor will have to work harder lugging the engine down even more. A trick to help with high, high side pressures at an idle, is to wire a pusher fan in front of the condensor that will come on when the compressor comes on. The extra air over the condenser will help keep high side pressures in check which in turn will bring low side pressure down making cooler air. I wired mine tthrough a relay using the AC switch on the dash. This causes the fan to run continuous when the button is pushed. My AC blows ice cold even on 100 degree days, idling or not.

Cold air at the stop light here!!! Turn the blue knob to the left :D.

you turned yours to the left and it worked?
i swear i turned mine to the right....
 
I seem to remember that I turned it to the left until the RPMs kicked up, meaning the AC was kicking in like the old days... But then again, maybe it was to the right... I was turning it back and forth until the higher RPMs. But I think it was CCW :confused:
 
mine does not blow REALLY cold anyway, but it was blowing outside/warm air, like it was on vent only, when i was at a stoplight. now it blows cool when i am at a stop light, more or less as cool as when i am moving. still not real cold though :(

but i am sure i turned the knob a few clicks to the right now that i think about it.

The blue knob doesn't control the RPM, it controls at what RPM the amplifier will turn on the A/C compressor clutch. There are other adjustments to increase RPM when A/C is requested.

from FSM: A/C Amplifier.
"Cut-off rpm 600-700 rpm. If the cut-off rpm is too high, turn the adjusting knob clockwise to adjust. If the cut-off rpm is too low, turn the adjusting knob counterclockwise to adjust."

yeah, it is definately to the right because i turned it all the way to the left while idling and the compressor turned off.

only problem now is it takes forever to cool off the cruiser because it is converted from freon is my guess.

gotta get those windows tinted!
 
Ok, my problem must be with the idle up vacuum solenoid because my compressor kicks off at idle but if puch the gas to get 1000 rpms the compressor kicks back on. Occationally it will kick up he rpms on it's own. So how do I go about fixing this problem?
 
all you who are real troopers will turn your a/c into an on board air set up like me. yes i am soaked with sweat throughout the 100 degree 8 month long neverending hell of a louisiana summer. but it is so humid here it doesn't matter b/c when you leave your cruiser, after two seconds, you are that soaked in sweat anyway. i just drive faster with the windows down. At least this way i have some security off road as i can run air tools, and inflate my tires with no worries. you a/c cold air guys should come to the dark side. air tools.... cold air.... air tools... cold air. like that really takes some thought.
