Replaced the bulb, still no luck. Drove down to an AutoZone and they said they didn't carry the proper relay, as it was a dealer part. So I guess tomorrow I'll have to drive down to a GM dealer and have them straighten this out. Anyone know if the one-year warranty for Certified Used will cover this? (figure bumper to bumper probably doesn't cover wear & tear items most likely)
Also, if anyone has a cheaper/quicker alternative to where I could procure said relay, please let me know!
