Hello... I have a 03 Trailblazer and am trying to find the location of the ODBII connection. I can't find where it's located for the life of me. Any help would be appreciated. thanks in advance.

Does your owners manual give you a hint?
The OBD11 law says it has to be within reach when sitting in in the seat but some I have to stand on my head to find them before i can rach them.
Some have covers over them.
Auto zone may have a locater for it or just ask them to read codes and see where they find it. :grinyes:

excellent idea. i will just stop by an auto zone and see if they can help me out. but before then if any knows where the location is it would be helpful and save a trip.

thanks in advance
