This is actually an easy swap out. Remove the electrical connection, remove the retaining bolt and pull out old one. I believe the sensor is located in the front passenger side of the engine on this particular model.

This one is easy. The clutch fan is not disengaging. Mine does the same thing after it has idled a while but then will release (wind noise stops) after getting up to speed.

Car stalls when ac or defrost on


Sounds like the compressor is dragging the engine down. The compressor runs in ac and defrost mode. You might try unplugging the compressor to verify.

Car shutting off when air condition is turn on causing it to stall


There is a switch that works the computer upon turning on the air conditioning. Upon turning the AC on the switch sends a signal to the computer to increase the RPM's to the engine so it will not die out

Engine stalls


Assuming you have the correct size battery, this really shouldn't happen! I am assuming the engine is idling at fairly low RPMs, so when the AC kicks on, it kills the engine? It might be that you need to drive the car for a bit so that the engine computer can "relearn" your settings, which disappear when you change the battery. Or, when your battery died, one of your sensors might have gone with it. There is a idle sensor on most cars that raises the idle RPMs when the AC comes on.
