Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.working after noon till just after midnight.
What model vehicle is this and which liter engine?
This fuse only powers the TCM and ECM, nothing else. So lets unplug both of those and try another fuse. If that fuse fails then we know its in the wiring from the fuse box to those modules. If the fuse does not fail, plug the ECM or TCM back up to see which module blows the fuse when plugged up. Can you do that?
