Thread: girl with car trouble

hey i drive a 200 ser and i've started having some trouble with it whenever i turn my ac on my battery light will turn on to and it blows out hot air does anyone know why its doing that and how to fix it

There could be many reasons for this but you could start by checking the battery and alternator. The a/c is drawing more power when its on so if the battery or alternator is going bad then that may make the light go on.
There could also be a short somewhere.
You should some how see if the ecu is throwing any codes and test the battery and alternator.

Yeah it sounds like the compressor is drawing too much current from the alternator.

That or the battery could be taking a crap thus the alternator having to work overtime.

i bought a new battery and terminals and put them in yesterday, the alt is good but now the battery light is staying on and when i put the e brake down the brake light is still on

You have a charging problem. Double check your battery connections are tight. Also check your fuses to make sure none are blown.

didnt you have the alt tested? sounds like the alt is junk.


battery light & brake light on = alternator fail

and clean. I've swapped batteries before and all of a sudden the car won't crank. Connections were tight and didn't look dirty but cleaned them up and it fired right up.

so its the alt i'm going to put the new one in tomorrow hopefully everything is going to run fine after that
