Voltage drops when running A/C
#11
When the battery and alternator were replaced the ones purchased meet or exceed the OE specs? Loose/Dirty connections will add resistance to a circuit. Check connections at the battery, the grounding points and the connectors of the affected circuits and clean as needed. There's too many possibilities that could cause the AC to blow warm air to give you a definitive answer. Your best bet for that is to have the system diagnosed to determine the cause.

What could cause this?
I have a 98 monte carlo and i posted previously though i should add a few more details to give a better understanding of my issue:
I drove the car all day just fine till i was on my way home first my ac went warm and low on Max setting so i turned it off along with my radio then my anti-lock, brake, change oil, low coolant lights came on soon after, after a couple minutes the volts and airbag lights came on, a few minutes later the day lights and interior lights started to fade until finally it died completely. I put a brand new battery in and I just had the alternator checked twice it was fine. The battery connections have been checked and are fine.

Can Anyone help?
I have a 98 Monte Carlo LS and I just replaced the battery and the alternator and my alternator is not getting a charge. In the past month I have replaced the battery 3 times and have put two different alternators on it, it will run for a day then the battery is completely drained. Does anyone have any idea what this is.
