What causes the noise in the car B-pillar?

[Steven]

Noise in the car B-pillar can be caused by issues with the air filter, spark plugs, ignition wires, gasoline, fuel filter, carburetor, or fuel pump. Reasons for B-pillar noise: If the noise is coming from the passenger-side B-pillar, try fastening the seat belt even when there is no passenger to see if the metal buckle is hitting the plastic panel below the B-pillar. Solutions for B-pillar noise: If the noise is due to excessive gaps between the inner plastic cover of the B-pillar and the steel plate, or minor deformation of the B-pillar causing friction between the plastic cover and the steel plate, follow the manufacturer's recommendations by injecting foam into the cavity where the noise occurs and applying 3M foam tape inside the B-pillar plastic cover. If the clips inside the B-pillar plastic cover are loose, simply tighten them after disassembly.
