1. Dirt and Grime Buildup: This is the most common culprit. Over time, dirt, grime, and even old lubricant can gum up the mechanism.
* Solution: Try cleaning the handle thoroughly. Use a degreaser (like WD-40, but be mindful that it's a temporary fix and might attract more dirt later; a dedicated contact cleaner is better) and a brush (an old toothbrush works well) to get into the crevices. Then, wipe it down with a clean cloth. Work the handle back and forth several times to help the cleaner penetrate. If this works, follow up with a light lubricant like silicone spray (avoid WD-40 as a long-term solution as it can attract dust and grime).
2. Worn or Broken Internal Mechanism: The internal components of the door handle, such as the springs and linkages, might be worn out or broken. This is more likely if the handle feels loose or unresponsive in addition to sticky.
* Solution: This usually requires disassembling the door panel to access and repair or replace the broken parts. This is a more involved repair and requires some mechanical aptitude. You'll need a trim removal tool to avoid damaging the door panel. Online tutorials and repair manuals specific to your 2003 Ford Focus are helpful here. You may be able to find replacement parts at an auto parts store or online.
3. Damaged or Frozen Lubricant: Old lubricant can thicken and become sticky, especially in cold weather.
* Solution: Similar to the dirt and grime solution, try cleaning the handle thoroughly with a degreaser. Then apply a fresh silicone-based lubricant. Avoid using heavy grease, as it can attract more dirt.
4. Exterior Handle Problem (if applicable): The stickiness may be limited to the outer handle, rather than the interior one. This could indicate a problem with the locking mechanism itself, which might need adjustment or replacement.
Steps to troubleshoot:
1. Clean First: Always start with cleaning. It's the simplest and cheapest solution, and often solves the problem.
2. Check for Loose Parts: If cleaning doesn't work, carefully examine the handle for any loose or broken parts before disassembling anything.
3. Inspect the Door Panel: If you suspect a more serious internal issue, prepare to remove the door panel. Look up a video tutorial for your specific year and model Ford Focus before you start.
4. Consider Professional Help: If you're uncomfortable disassembling the door panel or if cleaning and lubrication don't resolve the issue, take your car to a mechanic.
Remember to always consult a repair manual or online resources specific to your 2003 Ford Focus before attempting any repairs. This will provide diagrams and detailed instructions to help you avoid causing further damage.
