What causes the dashboard to heat up excessively?
The primary reason behind an oven-like dashboard is the greenhouse effect. When the sun’s rays pass through the windshield, they get trapped inside the cabin, causing the temperature to rise. This phenomenon is exacerbated by the dark-colored dashboard, which absorbs the heat instead of reflecting it. As a result, the heat becomes confined, making the dashboard feel like an oven.
Another contributing factor is the lack of ventilation in the cabin. If the air conditioning system is not functioning properly or is not used regularly, the hot air can become stagnant, leading to a buildup of heat near the dashboard. Additionally, driving in slow-moving traffic or being stuck in traffic jams can also contribute to the overheating of the dashboard, as the engine’s heat is not being dissipated efficiently.
