The electrical system within the cabin is a frequent trouble spot. Start by addressing the power window and door lock switches. These are known for failing; often, disassembling and cleaning the oxidized contacts with electrical cleaner can restore function. The blower motor resistor is another classic failure, often leaving you with only the highest fan speed; it’s located under the passenger-side dash and is relatively inexpensive to replace. For a major functionality leap, upgrade the factory stereo. A modern double-DIN touchscreen unit with Apple CarPlay and Android Auto integrates navigation, music, and hands-free calling seamlessly. This upgrade often requires a vehicle-specific wiring harness and dash kit, ensuring a clean, plug-and-play installation. To complete the modern feel, swap out all the dim, yellow incandescent bulbs in your instrument cluster, climate control panel, and dome lights for bright, white LED replacements. This simple, low-cost swap dramatically updates the cabin’s ambiance, especially at night.
