Did a search and came up blank. My financee's 03 Grand Am GT is throwing SES and ABS lights, along with traction control turning off. I'm suspecting problems with a wheel bearing (I have an odd, 'overrevving motor' sound as I increase speed) but I want to check the codes. I have an OBD II scanner, but the port isn't under the driver's side dash like it is in my Camaro. Where's the OBD II port on these things?

Her car just exited warranty, and like clockwork...problems. Suckage. :(

Sounds like you have the standard wheel hub assembling going out on you. I have had those same lights on for a year now, no problems except for the lights. I know my port in right under the steering wheel, kind of tucked under but it is there. The hub has to be replaced as a whole unit ... about $110 from my auto store.

yeah, you have to stretch a little first, then look directly below the steering wheel underneath the dash

Driver's side, underneath the dash. Atleast, that's where GM put mine.
