Bakersfield remains famous for its blistering summer sun and relentless dry air. This specific climate creates a harsh environment for every vehicle parked outside. Many drivers notice small cracks forming on their plastic surfaces over time. The heat does more than just ruin the aesthetics of a cabin. High temperatures actually penetrate deep into the sensitive electronic components inside the dash. Local experts at Brandon’s Transmission & Auto Repair see these common heat-related failures during the peak summer months. Understanding the science behind this damage helps you protect your valuable investment effectively.
The Science of Thermal Expansion in Plastics
The intense sun beats down on the windshield for many hours. This glass acts like a powerful magnifying lens for incoming thermal energy. Most dashboards consist of various polymers and specialized synthetic resins. These materials expand significantly when the internal cabin temperature rises quickly. Sometimes the plastic stretches beyond its natural physical limits during the day. The material then cools down and shrinks rapidly every single night. This constant cycle of expansion and contraction creates massive internal tension. Eventually the rigid surface loses its flexibility and starts to split.
Sensitive microchips may fail when the surrounding plastic housing becomes unstable. Now your infotainment screen or digital cluster might start to flicker. Protecting these parts is a main focus of Auto Repair in Bakersfield, CA.
UV Radiation
These rays attack the chemical bonds within the dashboard materials directly. This process is called photodegradation and it destroys the polymer chains. You will see colors fade before the actual physical cracking begins. The structural integrity of the dash weakens with every sunny day. Brandon’s Transmission & Auto Repair provides professional advice on using high quality sun shades daily. A simple reflective barrier blocks a huge portion of the radiation. This small step preserves the delicate electronics located right underneath the surface.
Preventing Expensive Electronic Failures Today
Keeping the windows cracked slightly allows hot air to escape the cabin. This reduces the peak temperature inside the vehicle during the afternoon. Sometimes a dash cover provides an extra layer of thermal insulation. You can save thousands of dollars by preventing these heat cracks early. The team at Brandon’s Transmission & Auto Repair understands how to maintain vehicles in this desert heat.
Conclusion
The combination of dry air and high heat is very destructive. Consistent maintenance and sun protection remain the best defences for any owner. You must stay proactive to avoid the high cost of component replacement. A cracked dashboard often signals deeper issues within the electrical systems. Taking care of the interior ensures the car stays functional and beautiful. Your vehicle deserves the best protection from the harsh California sun today.
