This is a time-based failure, not mileage-based. The rubber degrades from UV exposure and Florida heat regardless of how many miles you drive. If your Prius is over 10 years old, inspect these strips — they peel away from the door frame and start flapping, letting in wind noise, water, and debris.

What's Failing

There are four window weatherstrip pieces on the Gen 2 Prius — one per door. These are the rubber seals that run along the top of each door frame and press against the window glass as it rolls up and down. Over time the rubber hardens, cracks, and separates from the metal channel it's clipped into.

Symptoms: wind noise at highway speed, water intrusion around the window, or the rubber strip visibly peeling away from the door. In South Florida heat, this happens faster than in cooler climates.

OEM Part Numbers

Front Driver (Left) 75720-47010 ~$40

Buy OEM. Aftermarket weatherstrips for the Gen 2 Prius vary in quality and fit. The OEM strips clip in correctly and last. At ~$40 each from a Toyota dealer parts counter or online Toyota parts sites, the price difference over aftermarket is not worth the risk of a poor fit.

Replacement Steps

  1. Roll the window all the way down.
  2. The weatherstrip is held in place by a combination of clips and a channel that slides over the door frame. Starting at one end, carefully peel the old strip away from the door. It may be brittle — work slowly to avoid leaving broken clips in the channel.
  3. Clean the door frame channel with a rag. Remove any old adhesive or broken clip material.
  4. Starting at one end, press the new weatherstrip into the channel. Work along the length of the door, pressing firmly until all clips seat.
  5. Roll the window up and down to verify the strip doesn't catch or bunch.
  6. Check for any gaps at the corners where wind noise can enter.

Notes from the Field

The two front weatherstrips were replaced first — they take more abuse from door opening and closing and the driver's side goes first. The rears tend to follow within a year or two.

Replace all four eventually rather than just the ones visibly peeling. If one strip has degraded after 10+ years of Florida sun, the others are not far behind. Doing all four at once saves a second trip to the dealer for part numbers you could have ordered together.

These part numbers apply to the 2004–2009 Gen 2 Prius. Verify with your dealer if you're unsure — give them your VIN and they can confirm.
