I'm having trouble establishing a connection between the scantool and my 2002 Chevy Avalanche.  When you connect it, the green lights don't cycle like it is supposed to. 

First, I thought it was a defective cable but I tried it on my friends 2008 Lexus IS and it works fine.  So, the next choice is that my OBDII connector is bad.  The thing is though, I took my truck to AAMCO about a week back and they were able to read the trouble codes just fine.  I suppose that connector could have gone bad in that time but I think it is highly unlikely.

Does anyone know why this might be the case?

A blown fuse is the most likely culprit. DLC often shares one with the cigarette lighter.
