mbzman- i just got home from driving around for 45 min to an hour. the heater valve was not holding back the coolant from flowing so i plugged it up. the a/c seems to be only from the a/c now and not a mixture of heat from defrost and side vents. i went out and sat with the car idling and the ac seems to be fine since i did that; even when i accelerate no heat comes out and its working fine now.....BUT, its nighttime now and the temp is only 81 degrees, usually when its during the day and the temp is at 109 degrees it feels like the a/c is not cooling. also, i made a discovery while i was driving...i noticed my aux fans did not turn on low speed. could this be a main part of the problem? i read several other threads and people seem to speak about jumpering(?) two pig tail wires. i have no i dea what that means so i ordered the following pieces of equipment: AC/Refrigerant Temperature Sensor; Auxiliary Fan Switch at Receiver Drier, AC Cutoff Switch; On Cylinder Head; Blue Insulator with 2 Prong Connector; 130 Degree C, Air Temperature Sensor/Thermostat. I plan on replacing them all weather they work or not because i can't tell and i am a beginner when it comes to automechanics, but i can't afford to spend $$$$$ for something that i can learn how to do myself. what is the main thing that actually controls the aux fans and tells them to turn on low speed? because i know if i unplug the blue two-prong adapter thing on top of the valve the aux fans kick in high speed. please advise and thanks for your time.
