Isuzu Rodeo Window Regulator

Faulty Windows in an Isuzu Rodeo: When It Is the Window Regulator and When It Isn't

A window regulator generally works the same, regardless of whether it's in a manual or automatic window system. It's the part that transforms the rotating motion of the motor into the vertical movement that allows you to raise or lower the glass. When it breaks down, you'll have to remove your door panel and poke around inside. However, a bad regulator isn't the only reason for a faulty window. Knowing the differences can save you time, effort, and money. Here's a short guide you can refer to when trying to diagnose the problem:

The hand crank isn't working

For manual windows, it's an open and shut case; the window regulator and crank are all one piece. Open the door panel and check for loose, rusted, or worn moving parts in the regulator.

Nothing happens when the window controls are pressed

Age or obstructions to the mechanism can easily blow a fuse since window regulators use a lot of power. If pushing down on the button does nothing at all (ie. no sounds from the motor, glass isn't "struggling" to move), then you're looking at an electrical problem. Referring to your owner's guide, open the fuse box and check it out. If the fuse is in working condition and the window still isn't operational, grab a 12v test light and a schematic of your vehicle's electrical system. Test the wiring from the fuse to the switch, then from the switch to the motor. If, along the way, you find a connector that's loose or corroded, you've found what's blocking the voltage. Another possibility is a bad switch. For instance, if the passenger door's window can be moved by the button on the passenger door but not by the button on the driver's door.

You can hear the motor running when you press the button, but the window doesn't move

This is a sure sign of a bad regulator, or at least something physically stopping it from doing its job. Check for any obstructions or things that could increase the friction between the gasket and the glass. It doesn't take much added friction to make it too much for the regulator to move the window. As for the regulator itself, be on the lookout for damaged, disconnected, and missing parts. Jammed or sticky cables, broken or missing bushings, and corroded parts are all possible symptoms of an ailing window regulator.

  • How to Add Another Year to Your Isuzu Rodeo Window Regulator 27 February 2013

    When parts break down, what was once a minor convenience may turn into a major annoyance. A busted window is one such thing, turning tasks as simple as getting fast food at a drive-through into a balancing act. The window regulator in your Isuzu Rodeo is the main mechanical component in raising and lowering that glase pane, so it pays to know how to keep it in working order. All things have an end, but here are a few tips that should help delay that trip to the auto parts store:

    Fix loose or torn gaskets.

    These are the rubber seals along the bottom edge of the window. They protect the windor regulator by preventing foreign objects and moisture from entering the door's interior. This serves to keep the window obstruction free, which in turn puts less strain on the regulator. Keeping moisture out also saves the regulator's moving metal parts from rust and corrosion. Dust, which the gasket also blocks, can clog up and jam the window regulator's moving parts and joints. A loose gasket is easily solved by getting the appropriate weather-proof adhesive from the auto parts store. Be sure to clean off the old adhesive with lacquer thinner before applying the new stuff. For torn gaskets, you can try to use super glue to mend the tear with a rubber patch, but it's usually best to replace it.

    Reduce friction by applying lubricant.

    The gasket presses against the window tight enough to squeegee water off of it as you roll it down. There's a lot of friction involved as you raise or lower the glass, so apply some lubricant to ease the load on the regulator. Silicone spray or protectant should do fine.

    Straighten any misalignments.

    Misalignments put strain on the window regulator and its parts, such as cables, that could quicken wear and tear. These could be caused by foreign objects that interfere with the glass' path along the window track or loose connections that cause the door's internal parts to shift. Things like twigs, peanuts, and hardened snow aren't uncommon obstructions. As for the door's structure, make sure everything's bolted down nice and tight to prevent any unwanted movement.
