ON these hot days, the A/C starts out blowing nice and cold and as I sit in traffic and second electric fan kicks on the A/C begins to blow hot air. It continues to blow hot until the second electric fan kicks off, then the A/C starts blowing cold again. I can tell when the A/C clutch disengages, because there is a musty smell as the warm air starts blowing. When I am driving on the interstate at highway speeds, the air moving thru the grill seems to keep the engine bay cool enough that the second fan does not come on and the A/C works fine. Has anyone else experienced this issue or have any suggestions? Or does anyone have the A/C wiring schematic? I am starting to think that the second fan is drawing too much current causing the A/C Clutch Relay circuit to loose power, but I can't confirm unless I can get into the circuit and get some readings. Any help you guys can provide would be awesome.

Thanks
