1. Identify the Problem:
* Interior Handle Broken: This is usually a plastic part that's cracked or detached. The mechanism itself might still be functional.
* Exterior Handle Broken: This could be the handle itself cracked, the linkage broken inside the door, or the actuator (the motor that unlocks the door) malfunctioning.
* Handle Doesn't Work (Electrical Issue): The problem could be a faulty actuator, wiring harness, or even a blown fuse.
2. Repair Strategies:
* A. Broken Interior Handle:
* If it's just cracked plastic: You might be able to repair it with strong adhesive like epoxy or plastic welding compound. Clean the surfaces thoroughly before applying.
* If it's detached: You'll likely need to remove the door panel to access the broken parts and potentially replace the handle mechanism. There are many online tutorials showing how to remove the door panel on a 2006 Cobalt; search YouTube for "2006 Chevy Cobalt door panel removal." Once you have access, you should be able to see how to reattach or replace the broken part. Replacement handles are relatively inexpensive.
* B. Broken Exterior Handle:
* If the handle is cracked: Replacement is usually the best option.
* If the linkage is broken: This requires removing the door panel (see above). You'll need to trace the linkage mechanism to determine the break and repair or replace it. This is often more complex than a broken interior handle.
* If the actuator is faulty: This requires removing the door panel and replacing the actuator motor. You'll need to test the actuator with a multimeter to confirm if it's the source of the problem. Again, YouTube tutorials will be helpful.
* C. Electrical Issues (Handle Doesn't Work):
* Check the fuse: Consult your owner's manual to find the fuse for the power door locks.
* Test the actuator: Use a multimeter to check for power at the actuator connector.
* Inspect wiring: Check the wiring harness for any damage or loose connections. This often involves removing the door panel.
* Replace the actuator: If the actuator is faulty, it will need to be replaced.
3. Tools You Might Need:
* Screwdrivers (Phillips and flathead)
* Panel removal tools (to avoid scratching the door panel)
* Pliers
* Wire strippers/crimpers (if dealing with electrical issues)
* Multimeter (to test electrical components)
* Epoxy or plastic welding compound (for repairs)
* Replacement handle(s) and/or actuator
4. Important Considerations:
* Door Panel Removal: Removing the door panel can be tricky. Watch several YouTube videos before you start to get a good understanding of the process.
* Safety: Disconnect the battery negative terminal before working on any electrical components.
* Replacement Parts: You can find replacement parts online (e.g., eBay, Amazon, auto parts stores) or at a local auto parts store. Make sure you get the correct part for your specific year and model of Cobalt.
If you're not comfortable working on your car yourself, it's best to take it to a qualified mechanic. The cost of professional repair will likely be significantly less than the potential cost of making a mistake and causing further damage.
