Possible Repairs (DIY):
* Loose Mounting: If the mirror is loose but the glass and housing are intact, the problem might be with the mounting bolts or the plastic clips that secure the mirror to the door. You might be able to tighten existing bolts or replace broken plastic clips. This requires removing the mirror housing to access the mounting points. This is often doable with basic tools but requires patience. Online videos can help guide you through the process specific to your Avalanche year.
* Broken Plastic Housing: If the plastic housing is cracked but not shattered, you *might* be able to repair it with strong adhesive (like epoxy or plastic welding compound). However, this is a less reliable fix and the repair might not be aesthetically pleasing.
* Broken Mirror Glass: Replacing the glass itself is often the easiest and cheapest repair. These are readily available online and at auto parts stores.
When Replacement is Necessary:
* Shattered Housing: If the plastic housing is severely damaged, repair is usually impractical. Replacement is more cost-effective.
* Internal Wiring Damage: If the mirror's electrical components (heating element, turn signal, etc.) are damaged, it's often easier to replace the entire assembly. Repairing the wiring inside a complex mirror assembly is difficult.
* Significant Damage: Extensive damage makes repair more time-consuming and less reliable than replacement.
Before deciding:
1. Assess the damage: Carefully inspect the mirror assembly to pinpoint the exact problem. Take photos.
2. Check online resources: Search YouTube or other online forums for videos or instructions on repairing or replacing a 2002 Chevy Avalanche 1500 side mirror. This will give you a better understanding of the complexity involved.
3. Gather information on replacement cost: Check the cost of a new or used mirror assembly from online retailers or auto parts stores. This will help you decide if the repair is worth the effort.
In short, a minor loose mount or cracked glass is a possible DIY project. More extensive damage to the housing or internal components usually points towards replacement. If you're not comfortable with automotive repairs, it's best to take it to a professional.
