Hi there I have a 95 ranger 2.3 and when I went to smog it, the tech brought to my attention the check engine light did not work. He said it needed the bulb to be replaced. I replaced the bulb with a new factory one and it didn't work still. I checked all fuses and carefully looked at the cluster circuit board but everything looks good. I was told it might be the ecm so I changed it with my other ranger (same year) and it didn't solve the problem either. I even swapped out the instrument cluster and still nothing. All the wiring looks really good and I'm completely lost as to what to do. Any suggestions? Thanks everyone!!
