When it comes to your vehicle, true glory (or true failure) is always in the details. No matter how you look at it, you vehicle will ever be complete without every t crossed and i dotted - so take the time needed to keep things in great working order in every nook and cranny. In terms of Replacement Run Channel, then, you're talking about a small component that works with a small detail of your vehicle - but that doesn't mean it's not important. If you find you're having trouble rolling your windows up or down - or if you feel there's a bit of a draft or even some moisture literally slipping through the cracks - it could well be time for a Replacement Run Channel. Your run channel confines the glass of your window in a flocked, coated groove that keeps the window quite literally in line, as well as protected from damage, moisture, air leakage, and all manner of other troubles. Like any other portion of your vehicle, however, your run channel will start to show signs of wear after a period of time and heavy use - which is why a Replacement Run Channel can be so necessary.
