2001 sunfire, ac fan only trickles on

I recently inherited a 2001 sunfire from my girlfriend (don't ask), and out of no where the a/c fan stopped kicking on. At times the air still slightly trickles out cold. I have no idea how to check the fan or the fuse. Any help would be greatly appreciated as i now live in south florida and sweat when i try to go anywhere. I'm waiting on student loans and would love to find a fix.
thanks

SOURCE: Flickering Headlights and Dim interior lights

Definately an electrical problem....first off, check the battery and alternator connections to make sure they are tight. The problem has to be before the fuse box because the headlights and interior lights are on different fuses. It sounds to me like a loose wire, corroded battery terminals, or an alternator that is going bad. An alternator is a relatively easy and cheap fix. They cost about $100 and require removing a few wires, 3 bolts, and the serpentine belt.

SOURCE: 1999 pontiac sunfire over heats vents blowing cold air

Take the inlet & outlet hose off of the lines feeding your heater coil, where it come off the motor. Do you have good pressure on your water supply to your house????? If Yes. Flush the water thru the heater hose backwards from the diterction that the water normly flows from your car motor. Alot ot the time your heater core will just be plugged up and need to be backflushed. Also make sure that you do not have trash/ leaves in your heater box?????
You can also later on after flushing the H-core out, you can flush your motor, radiator & heater coil by dropping everything out and add water plus 1-can of old style Comett. This is very abrassive!!!! Run the motor for about 1-hour. Then drop all of it out. Put just water back into the system and run again about 10-minutes.Do this flushing about 3-times. You will see how clean your radiator will be, plus the cooler your motor will run.

SOURCE: Intermittent cold air on a 2001 Grand Am GT (3400 engine)

When you say tinker with the A/C. what did he do??? Just want to make sure he did not hot wire anything to activate the compressor at the max position. If the system is low on compressor oil the compressor will not active to keep it from getting damage or low on R143A. Most place now will recharge the A/C system for $50.00 since they know that you can by a recharge kit for around the same price, but you need make sure you don't over charge the system or damage will occur. If you not familiar with the recharge procedure, have it recharged by a shop and if it's full then the problem may be a  pressure switch and that takes around 5 min to replace and i am sure the shop will let you know before they try to recharge the system by hooking up the gauges to read the pressure in the system. Good luck and keep me posted, be glad to help you get some cold air again.

AC blows cold air, fans stop blowing


I think you have a "variable speed resistor" problem, it's overheating. It's an electronic device usually located near or attached to the AC motor blower that controls the fan speed. This is a common problem with aging AC blowers with electronic controls.

My 2001 pontiac sunfire 2.2L is making a clicking sound when it runs. what is making that sound? Is it the valves being worn or is it the valve springs being worn...


are you sure it is a clicking noise the 2.2 engine is bad for the ac compressor clutch going bad and making a metal to metal rubbing noise. the way to check this is while the car is running turn on the air conditioner and see if the noise stops if so all it needs if the ac compressor changed or bypassed till the spring. hope this helps.
