i have a 2000 blazer LS that sometimes the battery will go flat while sitting. it started with the rear hatch not opening. and then with the rear hatch opening when shifting from park to reverse. one time i tried to start and the hatch ajar light came on, and it set off the passlock. today i checked when the key was out and there was a draw of 1.7amps and when i pulled out the fuse for the pwr mirrors/pwrlocks it dropped to .18 amps. i would assume that is the drain on the battery. just wondering what can be done to fix the problem.

 

I had a problem recently with my battery dying and finally discovered the visor vanity mirror lights were not shutting off. 1996 S10 Blazer, sorry I cannot actually answer your other problems.
