Solution
1. Preparation
  • Gather tools: multimeter, thermal camera, basic hand tools (screwdrivers, socket set), brake cleaner, and safety glasses.
  • Ensure the vehicle is parked on a flat surface and turn off the ignition.
  • Disconnect the 12V battery to prevent any electrical issues during inspection.
2. Inspect and Replace Brake Components

  1. Remove Wheel:

    • Use a jack to lift the vehicle and securely place jack stands.
    • Remove the wheel lug nuts with a socket wrench and take off the wheel.

  2. Inspect Brake Pads and Rotors:

    • Check for wear on brake pads; if they appear burnt or excessively worn, replace them.
    • Inspect rotors for discoloration or warping; replace if necessary.

  3. Clean Components:

    • Use brake cleaner to remove dust and debris from brake components.
    • Ensure that all parts are free of oil or grease.
3. Inspect Electrical System

  1. Check Wiring:

    • Visually inspect all wiring near the motor and battery for signs of insulation damage or burning.
    • Use a multimeter to check for continuity and proper voltage in wiring.

  2. Replace Damaged Wires:

    • If any damaged wires are found, cut and splice in new wiring of the same gauge, ensuring proper insulation.
4. Check HVAC System

  1. Inspect Cabin Air Filter:

    • Remove the cabin air filter and check for any debris or burning smell.
    • Replace with a new filter if it appears damaged or clogged.

  2. Inspect HVAC Components:

    • Check the blower motor and fan for any signs of overheating.
    • Replace the blower motor if it shows any signs of burning or malfunction.
