My car wouldnt start the other day and I'm guessing it might have something to do with the cold weather (I also had the heater & radio turned on). So on my next try I turned them off and the car started but rather sluggishly. What could be the problem other than maybe the battery?

 

There's actually a section in the manual about this very problem. Check it out. Check the fuses.

 

Time to get a new battery.

 

Basicly we have a short life battery. My first one was replaced within 1 year of purchase. The second one is now 3 year old. it is easy enough to get tested at you local car parts store (free)
