2008 hummer h3 starting problem
Battery has been replaced, it was
okay for five days. Then wouldn't
start after being parked for 2 days.
check the interior light switch, probably the driver's door one. When it's sticky , the lights & a relay stay on , and put a load on the battery.
UPDATE & REPHRASE THAT :- I mean the one of the four door switches may be bad. the interior lights may go off, but a relay or some load may stay on. they have two circuits in those switches.
