Dear southernnx,

Hope you're well. Does your car have a sunroof? If so, it is likely that the drain tubes are plugged. I believe these tubes run to the center columns. As with any rubber tubes, probe them using lawn trimmer line. Round/blunt the tip, so as not to punch holes in the rubber. Push gently, to avoid compacting any debris.

The cowl is the metal section, between the hood's rear edge and the windshield's lower edge. The cowl is secured by screws at the end and a single screw in the middle. Once these fasteners have been removed, the cowl is removed by pushing backwards, and then lifting the front edge, so that it clears the hood. It is a good idea to tape thin cardboard sheets over the rear-most section of the hood, to protect it against being scratched during cowl removal.

At the ends of the cowl enclosure, you'll see the drain openings. Probe the rubber drain tubes gently, to push-out any debris.

If there is a lot of debris (leaves, pine needles, etc.) you may need to replace or re-seat the metal mesh, that excludes these things. If the factory-installed mesh has come loose, You can secure the mesh using butyl rubber.

Butyl rubber is a black, sticky rubber sealant, used by air-conditioning technicians. Butyl rubber sealant comes in tape (flat) or bead (round) formats. On the underside of the cowl's grille, press lengths of butyl rubber into the troughs in the grille's bars. Bed the mesh into the butyl, and apply more butyl, so that the mesh is held firmly. You'll not soon need to repeat the cleaning.

Hope this helps.

Yours faithfully,

Spook
