Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
hello sean, my name is ***** ***** for using just answer i will be glad to help u today i see u are having a issue with your impalla, i need to ask u this when u have taken the vehicle in has the shop checked for a voltage draw?
ok sean, at this point what needs to happen is, the person or technician that is going to look at this for u needs to install a digital volt meter between the negative ground cable, and the ground terminal at battery, put the meter on 10 amp scale remove the keys from the vehicle shut all doors wait 30 min for all computers to go into sleep mode at this point u will see what the draw is, if it is any more than 40 milliamps it is to much, once u find that there is a draw u need to start removing each fuse while watching the meter once u find out what fuse it is u can then figure out whats all on that circuit, then each item on circuit will have to be disconnected 1 at a time to find culpret. Being that the battery is dead every 3 hours that tells me there is a large draw from something, so this is what would need to be done.
there is many electrical components that would cause a draw like this. Some common areas of concern: add-on accessory, power seat switch, vanity mirror lamps, Body Control Module (BCM) blower motor radio alternator dome lights glove box lights door switch etc this is why a test with a dvm needs to be done
this type of a problem is electrical related and could take hours to diagnose even with the correct tech looking at it.
what type of garage have u been taking this vehicle to?
sounds good sean, looking forward to hear back from u. mike
