Ok, so I took the Trailblazer in for a routine inspection. They could not get a connection to the computer for the emissions test. Everything on the vehicle works fine. I tried to connect an OBDII and it wont interface with the vehicle either. The mechanic doing the inspection said he thought there was a fuse or link someware but he couldn't find anything wrong. Any Ideas???

There is a fuse, it also powers one (or more) of the 12 volt outlets.

Sorry, don't have my manuals with me. But, I'd start looking in the under the rear set fuse panel.

check the manual on the obdII it should give you some ideas of what to look for i cant find mine at the moment but it gives a list

I dont want to give you bad info but if its not a fuse i believe it would be pcm related? like i said im not positive on that hopefully someone can chime in and help out

test them with a test light.

iirc its the same fuse for the cig lighter in the underhood fuse box.
