The battery in my 1999 Nissan Altima died, now the ac clutch won't engage

SOURCE: Ac compressor will not engage when ac is on.

Check A/C compressor relay. When you say it seems to be full of gas(freon) have you actually put a pressure gauge on the system? If the pressure is too low, the compressor will not engage. If the compressor relay is functioning, check for power at the compressor clutch. If it has power to it and it still is not engaging, the A/C clutch may need replacing. It is usually almost as economical to replace the complete compressor with clutch installed than to just purchase a clutch. Keep in mind if you replace the compressor you should also replace the receiver/dryer also referred to as the accumulator.

Sounds like the blower resistor module needs to be replaced. Could also be the switch.

you call it the serpentine belt, we call it the fanbelt.it,needs tightening,slightly loosen the alternator, then pull away from engine and tighten belt, tight enough when you can move longest part of the belt, between pulleys, 1/2 inch in/out.
if squeel re occurs fit new belt.

Has the Freon been checked with a gauge to see if there is enough Freon to allow the system to work. Low or no Freon will not allow the compressor to engage. The low pressure switch is most likely activated due to low freon, and will cause this condition.
