Can you call your local Chevy dealer and have them provide the code? You may need to go there and prove proof of ownership. I purchased a radio for my '97 from a salvage yard and didn't need any code nor have I when I've had the neg batt cable off for an extended period of time. I think the first place is to the Chevy dealer and ask them. Hope this helps. Steve H.
Lead acid batteries use a weak solution of sulfuric acid in water as an electrolyte. Some of the water evaporates if it is not a sealed battery, causing the electrolyte to become more acidic than normal. Adding water to the correct water level makes up for the evaporation and restores the battery acid solution to its proper strength.
An auto battery could be leaking for a couple of reasons. The alternator could be overcharging the battery causing the leakage. Or the battery itself could have a short or other internal problem causing it to leak when charging.
There is a short in the switch. Replace it/.
something is causing a drain on the battery when switch is turned off
no
Dead cell in the battery or something is on drawing power from the battery.
Leaking from where on the battery, the caps? If so the charging system may be over charging the battery and causing the acid to boil out. Could be a voltage regulator problem.
Yes, that would definitely drain the battery.
haha..no
Drain? of what? Electricity or Battery Acid?if is electricity drain, the batteries last somewhere 3-5 YEARS, most of the time wen going sort trips to the store and around town the alternator it Doe's not have enough time to bring the battery to the proper level of charge, there for is causing the plates to replace the lose of electricity causing the plates to prematurely age and then one or more banks to dye making the battery useless, some part store or eBay they have liquid that you insert in each bank and dissolves the sediments , there for bringing the battery to it's previous level.GOOD LUCK:-)

Dirty battery connections created a spark when cranking the starter on a possibly overcharged/overheated battery causing an explosion.
