PROFIX Auto Repair • January 31, 2026

Welcome to the world of auto electrical services, where even the smallest component can have a significant impact on your vehicle's performance. At PROFIX Auto Repair in Norman, OK, we understand that navigating the complexities of your car's electrical system can be daunting. That's why we're here to offer guidance and support to ensure your ride remains smooth and safe.

Understanding Your Vehicle's Electrical System

Every vehicle is equipped with an intricate electrical system that powers everything from your headlights to your car's ignition. This system is critical for the operation of many components you rely on daily. Our team at PROFIX Auto Repair knows that understanding how these elements work can aid in diagnosing issues that may arise.

The Battery: Your Vehicle's Powerhouse

The battery is the heart of your car's electrical system, providing the initial jolt of energy required to start the engine. Regular checks and maintenance of the battery are crucial. In our experience at PROFIX Auto Repair in Norman, OK, we recommend testing your battery biannually to prevent unexpected failures.

The Alternator: Keeping the Energy Flowing

Once the engine starts, the alternator takes over, supplying continuous electrical power and charging the battery. A malfunctioning alternator might cause dimmed lights or a dying battery. At PROFIX Auto Repair, we suggest watching for signs like these to ensure timely repairs and replacements.

Common Electrical Issues and Solutions

From our extensive experience at PROFIX Auto Repair, there are several common electrical issues that many vehicle owners might encounter. Identifying and addressing these issues early helps prevent more costly repairs down the line.

Flickering Lights

Flickering or dimming lights often indicate an issue with your vehicle's electrical system, possibly the alternator or the battery. Our team in Norman, OK, is skilled at diagnosing the root of the problem and implementing effective solutions.

Electrical Component Failure

Components such as power windows, audio systems, and dashboard lights rely on a healthy electrical network. If these parts malfunction, there could be an issue with fuses or wiring. The technicians at PROFIX Auto Repair are adept at troubleshooting and repairing these intricate systems.

Proactive Maintenance Strategies

Maintaining your vehicle's electrical system is essential for longevity and reliability. Our experts at PROFIX Auto Repair advocate for proactive strategies that can save you from future headaches.

  • Regular Inspections: Schedule routine checks to catch potential issues before they escalate.
  • Battery Care: Regular cleaning and testing can prolong the battery's life.

Tesla Alignments: Protecting Your Tires from Uneven Wear at PROFIX Auto RepairTesla owners love the performance, but many notice tires wearing out faster than expected—especially uneven wear on the inner edges of the rear tires. This is common on Model 3, Model Y (including the newer 2026 Juniper models), Model S, and Model X. Common causes include: Heavy battery pack adding significant weight & Instant electric torque stressing tires during acceleration and regen braking. Factory alignment specs (often aggressive negative rear camber for better handling and stability) that accelerate inner-edge wear—even when "within spec." Everyday factors like potholes, curbs, or mileage causing slight drifts in toe, camber, or caster. The result? Premature bald spots on the inside, reduced tread life, noisier rides, lower efficiency, and safety concerns. A professional four-wheel alignment makes a big difference. At PROFIX Auto Repair, we use state-of-the-art equipment to check and adjust your Tesla to optimized specs—balancing performance, handling, and longer tire life. Many customers see dramatically reduced wear and better range after our service. Watch for these signs your Tesla needs attention: Uneven or rapid tire wear (especially inner rear edges) -Pulling to one side -Off-center steering wheel -Vibrations or unusual tire noise Don't let misalignment chew through another expensive set of tires. Schedule your Tesla alignment today at PROFIX Auto Repair—we're EV-friendly and ready to keep you safe on the road! Call us at 405-310-2279 or Click Here to book. Your Tesla deserves expert care.

As the temperatures drop and winter sets in, many drivers start experiencing frustrating car issues that seem to appear out of nowhere. At PROFIX Auto Repair, we've seen a surge in these cold-weather-related problems every year. The good news? Most of them are preventable with a little preparation and maintenance. In this post, we'll cover the most common issues our customers bring to us during the winter months and share tips on how to avoid them. 1. Dead or Weak Battery - Cold weather is the number one enemy of car batteries. Low temperatures can reduce a battery's power by up to 50-60%, making it struggle to start your engine—especially if it's already a few years old. Tip: Get your battery tested for free at PROFIX—we can tell you if it's time for a replacement before you're stranded. 2. Low Tire Pressure - For every 10°F drop in temperature, your tires can lose about 1 PSI of air pressure. Under inflated tires reduce traction, fuel efficiency, and increase the risk of blowouts on icy roads. Tip: Check your tire pressure monthly (including the spare!) and inflate to the manufacturer's recommended levels. 3. Thickened Engine Oil - In extreme cold, conventional oil can thicken, making it harder for your engine to turn over and potentially causing unnecessary wear during startup.firestonecompleteautocare.com Tip: Switch to a lower-viscosity synthetic oil rated for winter conditions. An oil change at PROFIX can make a big difference. 4. Frozen Door Locks and HandlesMoisture gets into locks and seals, then freezes solid, leaving you locked out of your own car. Tip: Apply a silicone-based lubricant to locks and rubber seals to prevent freezing. 5. Wiper Blade Issues - Wiper blades can freeze to the windshield, become brittle, or get damaged by ice buildup, streaking or failing when you need clear visibility the most. Tip: Replace old blades with winter-specific ones and lift them off the glass when parking in snow. 6. Reduced Traction and Getting Stuck - Snow and ice turn roads into skating rinks, leading to skids or wheels spinning without forward progress. Tip: Consider winter tires for better grip, and keep a traction aid like kitty litter in your trunk.Don't Wait Until It's Too Late!Many of these issues can be caught early with a simple winter maintenance check. At PROFIX Auto Repair, our experienced technicians are here to help keep your vehicle running smoothly all season long. Schedule your winter prep appointment today—call us or book online.

Well, Norman, Oklahoma decided to sprinkle a little Christmas magic on us in December, and by “sprinkle” we mean actual snowflakes the size of tortillas! While the kids are building wonky snowmen and half the town is attempting donuts in the Dollar General parking lot, we’re over here thinking about your poor car shivering outside.Here’s the quick, fun PROFIX Snow-Day Survival Guide:Slow Your Roll, Cowboy – Black ice doesn’t care how tough your truck looks. Ease off the gas, increase following distance, and pretend you’re driving Miss Daisy. Brakes Aren’t Suggestions – Pump those brakes gently like you’re flirting, not stomping like you just saw your ex at Target. Wipers Up, Problems Down – Before the snow hits next time, flip your wipers up. No more doing the ice-chip shimmy at 6 a.m. with a cereal bowl in one hand. Battery Hates the Cold More Than Your Mother-in-Law Hates Your Cooking – Cold weather can sap 50% of your battery’s cranking power. If your car’s been starting slower than a Monday morning, swing by PROFIX. We’ll test it faster than you can say “hot cocoa.” Tires Matter, Bro – If your tread looks slicker than the roads, it’s time for new shoes. All-seasons are cute until they’re ice-skating. Bonus laugh: Yes, someone already brought us a car this morning because “the traction control light looks like a sad face.” It’s okay, we speak fluent car emotions.Stay warm, stay safe, and if your car starts making noises that sound like it’s auditioning for a polar bear documentary, you know where to find us—we’re the warm shop with the coffee that doesn’t taste like regret.Drive slow, Norman. We love you (and your car) too much to see either of you in a ditch.— The PROFIX Crew
