How can I pull the codes from a 04 cavalier? I know in the olden days you could bypass the plug under the dash with a paper clip. Can you do anything like this?
No. need a ODB II code reader. You can go to Autozone and they will read the codes for free.

I'm in Canada. We don't have a free service within the city that does this.
I wish!
1: an ELM327 OBD-II Code Scanner on eBay
2: A laptop with Windows
3: scantool.net software which is free
