Trouble codes

[BoB393]

Hi; I'm sure this has been asked many times before but I can't find it. Does anyone know if I can access the trouble codes on my 2003 limited without an OBD scanner. Perhaps through the climate control like many other GM's. Thanks

No other way, you will need an OBDII scanner on this particular vehicle. Take it to AZ, O'Rielly or Advanced & ask for a scan, they do it free!

Thank you. I'll do that.
