My ac fan is spinning counterclockwise resulting in overheating
I replaced my ac fan motor, I did the connection using the material that comes with the motor, including the capacitor. when the fan is on, it get very loud, and within a short time it shut itself up. What do I need to do to get the motor spin clockwise? I would really appreciate some help

There is probably only 1 wire leading to the F or FAN terminal on the capacitor. You remove the 1 wire to the fan side of the capacitor and connect it to the new fan capacitor. Then you take an extra wire that you will need to make, buy, or find, and connect it from the opposite terminal on your new capacitor. Meaning the other side that of the capacitor. Then connect that new wire from the new capacitor back to the old capacitors C or COM terminal. Clear as mud I know, but basically you run your fan capacitor wire to the new capacitor, then the other side of the capacitor runs back to common on the old capacitor. And beware! Those things can hold a charge!!! Disconnect all power & discharge the capacitor! Hope this helps
If you hear a clicking noise coming from the compressor there is about a 80% chance that the compressor is dead. But you'll have to call someone out to be sure. If the fan motor behind the grill is running (condenser fan) then the compressor should be running and vice versa. If the compressor is hot as a pistol and clicking and the fan motor is not working then it may cool down if you shut it off and you might just have a bad fan motor. With power turned off the condenser fan motor should freely spin. Compressor have a 5 year warranty from the manufacture not including labor and additional materials. Hope this helps.
There is. Unfortunately it is on the main circuit board. To check pull the circuit board out and examine the bottom in search of a scorch mark where the circuit has overheated and burst. If so, replace the board. Usually if I hear that hum it means the motor itself has burned out and needs to be replaced. since the squirrel cage spins free, it's possible that the motors capacitor isn't right, which caused the eventual burnout. be sure to check that if you replace the motor, just read the motor for the number and use a multimeter to check the capacitor. best of luck to you.
you know the water pump for that particular car is on the other side? is driven by the cam... either your water pump is not working,(to remove water pump you need special tool) did you change the termostat? temp. sensor?
mechanical fans, most overheating problems are caused by
a faulty fan clutch - though a missing fan shroud can reduce the fan’s
effectiveness by as much as 50 percent (depending on the fan’s distance
radiator), which may be enough to cause the engine to overheat in hot
when working hard.
fan clutches are a common and often overlooked cause of
overheating. The shear characteristics of the clutch fluid gradually
deteriorates over time, with an average loss in drive efficiency of
rpm per year. Eventually slippage reaches the point where effective
no longer possible and overheating results. (On average, the life of a
clutch is about the same as a water pump. If one needs to be replaced,
usually does too.)
the fan clutch shows signs of fluid leakage (oily streaks radiating
outward from the hub of the clutch), spins freely with little or no

jumping the fan directly to the battery. If it runs, the problem is in

Shut the power off to the unit, spin the fan blade to see if it spins freely. If it doesn't spin freely, (there appears to be a little drag when you spin it),the bearings are bad, if it does spin freely, then try moving the motor shaft from side to side if there’s any play in the shaft side to side then the bearings are worn and motor needs replaced. Then, check the capacitor, if it’s bulging even slightly, the capacitor is bad and needs replaced. Most of the time people replace the capacitor if motor seems ok. If capacitor is ok, turn power on to see if the motor is getting the proper voltage, if it is and not trying to run, then the windings are probably open, the motor's bad and needs replaced.
Feel the motor and see if hes hot ...... spin the fan by hand and see if it spins freely if not the bearings have seized up. So either rebuild the fan motor simply by replacing the bearings and oiling them and that should fix your problem. IF the fan spins freely OHM out the fan and make sure there is no shorts or openings in the fan. if your fan motor checks out good both mechanically and electrically then your next step is to check the capacitor and control board
