GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hello, my name is***** you know what diagnostic codes your getting? After installing radio it will be locked and you will need dealership to program new vin into radio.
Does vehicle seem to run fine now? Do you notice any performance related problems or any problems at all besides check engine light?
The check engine light can come on for many reasons, many of them only emission related. If vehicle still runs fine then you should be fine to drive without worrying about breaking down but that does not mean forget about the problem, it just means you can continue to drive until it is fixed. You can have diagnostic codes checked at your local parts store for free, write them down, and reply to this answer at any time without additional fees so I think that is the best first step. With codes I can give you possible/common problems, testing/repair instructions, and costs. Let me know how it goes or if you have more questions, thanks.
No problem, make sure to let me know what codes are when you get a chance. Thanks again and have a great day!
