02 impala problems

[demetrius316]

I have a 02 impala with a 3400 motor in the the first problem that im having is the a/c blows from the upper and lower vent only.The next problem that im having the low coolent light is on and the radiator is full.The car is not overheating or any thing.The next issue is the low oil presseure light comes on and the oil pressure is fine.And the last problem is I could be driving and the car will just die.It will crank right back up and there is no check engine light on.And help on these issue is greatly thanked.
