Rigid, or scissor, design regulators are used in some current and most early vehicles in the 2000s and older and are used frequently on rear applications. This O.E. design tends to fail at about half the rate as cable style regulators. The amount of time it takes to replace this regulator makes most consumers and installers prefer to replace both the window motor and window regulator. Once a consumer replaces the entire assembly, all future replacements have to use this part type. All connectors on these parts are an exact match to the O.E. motor to ensure an easy replacement.
