2000 S-10 Blazer. I checked all the fuses under the hood. battery voltage after setting 3 days was 11.97. all fuses read 0 draw with these exceptions.
ECM B read 10.98, MIR/LKS read .02 & RR/WW read .03
I have no idea if the ECM is supposed to have volts or not. I assume the MIR/LKS is the power mirror adjustment and LKS is the power door locks. why would they draw? and lastly why would the rear window washer draw. in post II, I found the cruise control had a .02 draw.
all totaled, I guess it would knock the battery down after setting a few days. the question is, how do I cure this?
any help will be appreciated.
Thanks Rod in AZ

I was setting inside the Blazer tonight, when it was dark, to check for any light which might be on. I found something which I thought was strange. the driver power seat adjustment works when the key is off! is that normal?

Yup, my 95 has power without the key.

One of your locks could be bad. Or a switch.

ECM should power down with key off.
