Volvo Repair: 2001 v70 repeated low voltage warning (new battery), plastic casing, power locks

Question
Hello Mr. Patricio. I have replaced my battery three times, and the alternator
once. The car was running a little sluggish after the alternator was replaced.
The repair lasted 29 hours. I am once again receiving a low voltage warning.
Before this mess the radio has changed stations when I turn the wheel, the air
conditioning works intermittently (recharged  three months ago), one
headlight has burned out as in burned the plastic casing and been replaced
and burned out immediately afterwards, the brake light on the same side
burned out, and the power locks work sporadically. I'm sorry this is so long
but there seem to be so many problems. I'm taking it in but I thought I might
get some advice first. Considering I wouldn't even know how to change the
oil. Thanks for your time!

Answer
cristy, sounds like a bunch of issues and unfortunately on those newer cars, everything needs to be hooked up to the computer to find out whats wrong with the car.  There is obviously a drawn killing the battery.  Sounds like a module problem but without scanning the car, I would only be guessing.  I suggest a Volvo shop or unfortunately, the dealer.  Roger
