I had the same issue that StaceyLee stated earlier. I put a new ground wire next to the battery, because it became corroded off. About 600 miles later had another ground wire come lose. I could not find it. Took it to the shop and they had replaced it. About 5 days later my cruise control no longer worked. Soon after that my air bag light came on. My headlights are having issues. Issues being that when I turn the headlights on they are on until I hit a bump they shut off completely. My instrument panel does the same as the headlights. They work and will sometimes stop working. If I smack the dash they begin working again. I feel like this a a ground wire issue but have no idea where to look the ground that connects to either the engine or I was possibly thinking to the PCM. I know the basics about car care, which is why I found the first bad ground. I think the shop repaired the ground to the engine, but it may have easily become disconnected.
My question is this: where can I locate the ground wire to the PCM, engine and any other ground wire besides the one located next to the battery?
