Truck Electrical, A/C & Inspection Services

Beyond the engine and drivetrain, a modern truck relies on a network of complex systems for safety, comfort, and functionality. At Performance Authority in Bend, we are experts in diagnosing and repairing these intricate components. When you’re facing frustrating electrical gremlins, a weak A/C, or need a comprehensive vehicle health check, our specialists have the advanced tools and expertise to provide a definitive solution.

Expert Electrical System Diagnostics & Repair

Is your truck plagued by a flickering light, a dead battery, or a feature that works intermittently? The complex wiring harnesses and control modules in today’s trucks can make electrical issues a nightmare to solve for general mechanics. We are truck electrical repair experts who excel at tracing and fixing these problems.

  • Advanced Diagnostics: We use dealership-level scan tools to communicate with your truck’s Body Control Module (BCM), Powertrain Control Module (PCM), and other systems to accurately identify fault codes.
  • Parasitic Draw Testing: We can locate the source of a battery drain that leaves you stranded.
  • Wiring Harness Repair: We skillfully repair damaged or corroded wiring, saving you from the high cost of a full harness replacement.
  • Component Repair: We service and replace alternators, starters, batteries, sensors, and switches.

Truck Heating & Air Conditioning (HVAC) Service

A fully functional climate control system is essential for comfort in Central Oregon’s dynamic weather and critical for safety via window defrosting. We offer complete truck A/C repair and heating system services.

  • A/C Service & Recharge: We diagnose leaks and other faults, repair or replace components like compressors and condensers, and perform professional refrigerant recharges to restore ice-cold air.
  • Heater System Repair: We handle common issues like failed heater cores, blend door actuators, and blower motors to ensure you have reliable heat.

Comprehensive Vehicle Health & Pre-Purchase Inspections

Making an informed decision is crucial when buying a used truck. Our comprehensive pre-purchase truck inspection is the most valuable tool a buyer can have. We perform a bumper-to-bumper evaluation, including a detailed engine assessment (especially for diesels), a full systems check, and an undercarriage review to identify hidden rust, leaks, or damage. This service provides the peace of mind you need to either buy with confidence or walk away from a bad investment. We also offer full vehicle health inspections for current owners who want a complete status report on their truck before a long road trip or a change in seasons.

FAQs

For most diesel trucks, we recommend full maintenance every 5,000 to 7,500 miles, depending on usage and driving conditions. Regular upkeep—including oil changes, filter replacements, fluid checks, and inspections—keeps your diesel running stronger, longer.

Our transmission service includes fluid inspection and replacement, filter changes, diagnostics, and full rebuilds or replacements if needed. Whether you’re dealing with slipping gears or delayed shifting, we’ll restore smooth performance. 

Common signs include uneven tire wear, bouncing after bumps, steering instability, or a rough ride. We inspect shocks, struts, springs, and bushings—then repair or upgrade your suspension for better handling and durability. 

We inspect pads, rotors, calipers, brake fluid, and lines for wear or leaks. Whether you need a basic pad replacement or a full brake system overhaul, we ensure your truck stops safely and reliably every time. 

Warning lights, poor fuel economy, rough idling, or lack of power are all signs your engine needs a checkup. We use advanced scan tools and hands-on testing to pinpoint issues—no guesswork involved.

Diesel engines run hotter and under more pressure than gas engines, making clean oil essential. Routine oil and filter changes reduce wear, boost efficiency, and extend engine life—especially if you haul or tow frequently.

We perform a full visual and mechanical inspection—covering the engine, transmission, suspension, brakes, tires, HVAC, and more. You’ll get a detailed report so you can buy with confidence or walk away informed.

Yes. We provide customizable fleet services to keep your vehicles on the road and out of the shop. From regular oil changes to DOT inspections and major repairs, we tailor our service to your business needs.

If your cab won’t warm up in winter, your A/C blows warm in summer, or your engine is overheating, it’s time for HVAC service. We inspect compressors, radiators, belts, hoses, and thermostats to keep things cool—or warm.
