1990 Ford F-150 — footwell gets wet only after heavy rain

Write down what you already tried. A second data point from another 1990 Ford F-150 owner helps more than a generic diagnosis. I'd do that before spending real money. Do that first. I'd rather be boring and correct. If this is nothing, great. I want that in data.

Don't overfit one forum story to your car. If it still isn't clear on the 1990 Ford F-150, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. I'd want a dollar figure or a measured spec, not 'should be fine.' I'm in no rush to be a hero on it.

Owner notes beat generic advice here. On the 1990 Ford F-150 in Nationwide, I'd fix the thing you'll notice every day before chasing spec-sheet extras. Then you'll know the next fork. On “150 — footwell gets wet only after,” that was the fork that mattered for me. Run the total, not the monthly, before you commit. Wrote this up on my lunch break.

Following up on 150 — footwell gets wet only after: still happening, but I have better notes now. I'd rather look cautious in this thread than stuck later.
