1. Disconnect the Battery: This is crucial to prevent accidental short circuits or damage to the electrical system. Disconnect the negative (-) terminal first.
2. Remove the Mirror Housing: This is the most involved step and varies depending on the mirror type. Generally, you'll need to:
* Locate the retaining clips or screws: Carefully examine the edges of the mirror housing. There might be small clips hiding under trim pieces or visible screws holding the mirror to the door.
* Gently pry the housing loose: Use a plastic trim removal tool or a flat-head screwdriver wrapped in cloth to avoid scratching the paint. Work your way around the perimeter, carefully releasing the clips or removing the screws. Be patient; it's often tricky.
* Disconnect the electrical connector: Once the housing is loose, carefully disconnect the electrical connector for the mirror's power and heating elements (if equipped). This connector is usually located near the base of the mirror arm.
3. Access the Tilt Motor: With the mirror housing removed, the tilt motor mechanism should be visible. The motor is usually a small, compact unit that's either directly connected to the tilting mechanism or attached via a small gear system.
4. Carefully Inspect and Repair/Replace: Once you have access, you can inspect the motor for damage, worn gears, or other issues. Replacing the motor usually involves unbolting it from its mounting location and connecting the new one. Pay close attention to how the old motor was connected to understand the correct reassembly procedure.
Important Considerations:
* Consult a repair manual: A repair manual specific to your 2002 Chevy Trailblazer will provide detailed diagrams and instructions for removing the mirror assembly. This is highly recommended.
* Take pictures: Before you start disconnecting anything, take lots of pictures to help you remember how everything goes back together.
* Patience is key: This process can be fiddly and time-consuming. Don't rush it.
* Professional help: If you're not comfortable with automotive repairs, it's best to take your Trailblazer to a qualified mechanic. Improper disassembly could damage the mirror or surrounding parts.
Remember safety first! Always disconnect the battery before working on any electrical components. If you are unsure about any step, seek professional assistance.
