Auto Electrical Repair in Sun Valley & Glendale

Electrical problems are among the trickiest automotive issues to diagnose. Modern vehicles contain miles of wiring and dozens of electronic control units, and a single faulty connection can cause a cascade of symptoms. From a car that won't start to flickering lights and dead power windows, electrical issues require an experienced hand.

At A Plus Auto Shop, Armik has the diagnostic tools and expertise to track down even the most elusive electrical problems. We trace wiring faults, test components, and repair or replace electrical parts to get everything working properly again.

What We Offer

Our Electrical Systems Services

Comprehensive electrical systems services for all makes and models at A Plus Auto Shop.

Battery Testing & Replacement

A weak battery causes slow cranking, dim lights, and no-start conditions. We test your battery's charge and cranking capacity, and replace it with the correct size and type if needed.

Alternator Repair & Replacement

The alternator charges your battery while driving. A failing alternator causes dim lights, dead batteries, and warning lights. We test alternator output and replace failing units.

Starter Motor Repair

If your car clicks but won't crank, or the starter grinds, the starter motor likely needs attention. We diagnose and replace starters to get you back on the road.

Wiring Harness Diagnosis

Corroded, chafed, or damaged wiring causes intermittent electrical issues that are hard to pin down. We use wiring diagrams and testing equipment to trace and repair wiring faults.

Lighting & Fuse Repair

Blown fuses, burnt-out headlights, and malfunctioning tail lights are safety hazards. We diagnose the cause of repeated fuse blows and replace bulbs and lighting components.

Power Window & Lock Repair

Stuck windows and non-working door locks are common electrical issues. We diagnose whether the problem is the motor, switch, regulator, or wiring, and repair it accordingly.

Common Questions

Frequently Asked Questions

Answers to common questions about electrical systems at A Plus Auto Shop.

Why won't my car start?

A no-start condition can be caused by a dead battery, failed starter, bad alternator, faulty ignition switch, or fuel system problem. We diagnose the exact cause and provide targeted repairs rather than guessing with part replacements.

How long does a car battery last?

Most car batteries last 3 to 5 years, depending on climate, driving habits, and electrical demands. Extreme heat — common in Southern California — can shorten battery life. We recommend testing your battery annually after the 3-year mark.

Why do my car lights keep flickering?

Flickering lights usually indicate a charging system problem, often a failing alternator or loose wiring connection. It can also be caused by a weak battery or corroded ground connection. Have it diagnosed to prevent a breakdown.

How much does an alternator replacement cost?

Alternator replacement costs depend on your vehicle's make and model. We provide competitive pricing and a detailed estimate before any work begins. Call (818) 500-1939 for a quote.
