Truck is parked at mom's place, the tree has been dropping leaves. Little oval ones that go right down the slots Last year, I taped the cowl vents. Didn't get to it in time this year. Fabbed up a ridiculous vac/funnel/tubing suction device, shoved it in the vents, and it would grab about three leaves at a time, which I then had to remove one at a time. Nope!

So, I thought... what are the chances that those phillips screws would turn? Found out, good! They all came out like the truck was built yesterday. Released the clips on the wiper arms, pop pop off with the arms. Pulled the cowl. Can't believe how easy. Got the leaves out, and was rewarded with a big ancient mouse nest from down in the passenger side! Happy to see that there was no rust in the flat panel below the vents, despite my truck sitting outside all the time.

Don't be afraid to take this piece off to clean.
