Hello all,
I have a 2004 Grand Prix GT with 85K original miles. I absolutely love the car and want it to last as long as possible. Recently my check engine light came on, however, the OBD2 port is not allowing a scan tool to read the codes. I've tried my personal scan tool, Autozone and Advanced Auto scan tools - none will read the codes. I then went into my fuses to check the "auxiliary power" fuse to ensure it was not blown. The fuse is good. What else can I do to determine what the problem is? I'd prefer to stay away from the dealership at all costs because I know they will charge me a ton of money to even look at the car. Any thoughts or ideas is greatly appreciated!
Thanks!
