Weak AC on idle, but gets back to normal when car is running

[dr. d]

That's exactly my recent concern. Car is cool again when running, but no coolness when in idle mode (like AC is 50% off and FAN only). Do i need to replace parts, clean system etc? thank you very much tsikot experts

i had the same problem with my non-corolla/non-honda car. it seems, i had a leak and had no freon. the "cool" i experienced when running at speed, was simply the effect of compressed air expanding.. everything went back to normal when i had the leak remedied and the freon refilled.
and i agree.. the aux fan should turn on when the compressor is powered.
perhaps the prince is confusing over the aircon's aux fan and the car's radiator fan. perhaps someone tampered with the original wiring.
