Something on the backdoor of my suv is making banging noise when started. My mechanic said it was blower motor or actuator or whatever. He fixed it. A few days later, the noise came back with longer banging noise in different tone and longer duration. My mechanic said ir was a faulty part. So he fixed with another part. It was good for about 4 days… then the noise came back… can you help me? ---

Was it an OEM part he installed? Some aftermarket parts don’t work well right out of the box. ---

check the cargo rails on the roof. If you have cross rails, one might be loose. I had a banging noise a while back on my van. It sounded like it was inside the side door, but was really on the roof.
