FROM: LustyKid;

First: How old is your battery--more than 3 years old to 5?. Is it the type where you add water to the cells, Take off caps and see if there is any water in them. If no water add distilled water to each cell up to the split ring. Check to make sure your battery connections are clean and free of corrosion. If all that is within limits then you..........Probably need a new one.

If the battery is OK, have the output voltage check for the alternator. It should be around 13 - 14 volts being put out. If no good replace the alternator. Hope this helps.

Hi Jeff
Fault code P0456 means evaporator emission control small leak detected.
you need to check the tank filling cap, evaporator valve, hoses and connection for leak.
Good Luck

Look at visor lights are they turning off? You need to do a parasitic draw test to isolate draw. without a meter testing draw its hard to locate source of draw. Dirty battery connections can also not let charge get to battery.

My 1999 chevy silverado will not consistently start and when it does run will die when I come to a stop, the battery indicator is on and none of the electrical works in the cab?


have your alternator checked. your chevy is probably running on the battery which is probably only receiving a particle charge from the alternator. I had a chevy did the same thing when ever the alternator was going out.

Battery light on, battery ok


How long has the light been on? Although the battery is ok, it most likely means it is not charging. Take the suburban to a parts store for a free check of the system. They should be able to determine if the alternator not charging.

Rear a/c not blowing cold, front works fine.


you may not have enough refrigerant. a low charge can cause the rear in this dual system to not work for beans. charge with a can of uv and find the leak. fix the leak. evac the system and recharge. i think you take 4 lbs, but check the accumulator sticker. you may want to just change the accum at the same time.
