Overheating with AC on
Ever since temps started hitting around 110 my car has been.. not overheating..but running at 1/2on the temp gauge which is high for this car. It does it no matter if im driving or in stop and go traffic.
Normally it wouldnt bother me but as the temp goes up to 1/2, the ac gets warmer and warmer and when i sit still for to long it just starts blowing warmair. Im thinking its some sort of cooling problem involving not getting enough air through the radiator, but then, it does it when im driving at speed too.
The AC works great before the sun is up and after it goes down though.
With the AC off it runs at 1/4 like normal even when its 110 outside. What gives?
Oh yea, I also have a small 14 inch electric fan IN ADDITION to the stock clutch fan.
Theres no bubbling in teh coolant, and the engine is a rebuilt with about 5k miles on it.

Might also have a compressor in the beginning of its end. Take a moment to listen to the compressor and see if its making weird noises. Remember all of our cars are at least 12 years old. Components such as the ac compressor are ready to fail just in age alone.

The A/C not being able to keep the air cool is probably a seperate issue, most likely low refrigerant. Run the system for five minutes (or until the coolant temp gets too high) and check the sight glass on top of the receiver/drier when the compressor's clutch is engaged. If you see bubbles passing through the glass, it needs recharging.

I'm hardcore. I hate losing power to AC.
