hey guys. i'm the proud new owner of a 99 s10 blazer and i have an electrical issue. my battery gets drained after a day or two. i've narrowed the source to RDO BATT circuit. when i pull the fuse, i get normal battery draw, but with the fuse in i get excessive battery draw. can anyone help me out?? thanks in advance.

 

There are only 3 things on that fuse, the radio, instrument panel, and electronic climate control module(if equipped). Put your fuse in, hook up your amp meter and watch the draw. Unplug the radio, watch to see if the draw drops. If it does, you're looking at a radio. If not, do the same for the IPC, and the ECC.

 

awesome. that's what i'll do. how do i know if i have electronic climate control?? i don't think i have it because i just have a **** to turn to blue or red. also, what's the easiest way to unplug the radio? do i have to remove it??

 

Your climate ontrols will either be digital, or analog(just regular ***** to adjust), The best way to check the radio, is to accually remove the radio and unplug it
