October 1st, 2012 05:17 PM #12Your auxiliary fan, supposing its still in optimal working condition, should be fine. If it shuts off too soon, then you'd notice your engine temp to spike as well. This is assuming your condenser is in front of your radiator.
But since its crank driven, your issues migrate to something more along the A/C's subsystems.
The problem in those situations normally have more to do with your refrigerant levels. If after a full charge and this is still a problem the A/C's internals may need to get some work done.

it would greatly help if you specified your suction (low side) and your discharge or head (high side) pressures when the symptom begins to show. this way, the numbers on both gauges tell you as to what is wrong with your system rather than guessing and hoping somebody will come across luck.

October 9th, 2012 06:55 PM #14my old car (front engine-rear wheel drive, no aux fan) would default to fan in heavy traffic. i solved the problem by having an aux fan installed in front of the radiator. but you should have your vehicle seen by the aircon folks. too many possibilities, as the guys here suggest.

Before you dive into technical bits, try adjusting your thermostat a little bit on the warmer side. Your evaporator may be icing over due to your thermostat setting being too cold.
That, or you need to have your refrigerant levels checked.
as an aside, in the olden days, anyone who does not move 'ala luksa during Holy Week, especially...
