1999 GMC Safari Question: CHECK ENGINE LIGHT KEEPS COMING ON
Answer #1Bret Bodas December 31, 2010, 16:55Master
Do you know the diagnostic trouble codes that are setting off the light?
Answer #2mastertech6371 December 31, 2010, 20:54Master
you said checked, not repaired. re seting the light only lets the problem remain and the light will come back on till you have a diag performed and repairs made to correct the issue.
