2007 Chevy Suburban is dying while it sits. Battery and Alternator test out fine. What can I do to fix it?
My 2007 Chevy Suburban will die while it sits overnight or while I am at work. I
have taken it in and the battery always tests out fine and the alternator tests
out fine. I got tired of having it jumped, so I bought a charger battery that I
keep in the car with me at all times. For the last two months, I have had to
jump start it almost 1 time a day, on average. Sometimes more, sometimes
less. What is wrong? What can I do to fix it without spending a bunch of
money for them to tell me they don't know?
