2000 S-10 Blazer. I have been having this problem for several months. I found the sunvisor lites were staying on. I finally cut the wires. now the battery continues to drain. I disconnected the ground for 4 days and the battery only dropped from 12.54 to 12.44. I hooked it back up and over nite it dropped from 12.44 to 11.92. I pulled and checked each dashboard fuse. most read 0. 4 read .02 to .04. the cruise control read .04, why would the cruise read anything, when the switch is off? also some fuse labeled SIR had a .04 drain. I have no idea what that is.
I have not checked anything in the underhood box.
Winter is coming [yes even in Arizona it gets cold] I dont want to have a dead [or almost] some cold morning.
thoughts or help will be greatly appreciated.
Thanks Rod in AZ

I had a similar problem on an'83 Z28. Turned out the ecm was drawing 5 volts even when the engine was off.

It was under warranty, but I think they swapped it for a new one.
