Baldwin Park & Surrounding Areas
Modern vehicles are rolling computers. When the electrical system falters, nothing else matters. We diagnose and repair it all.
Advanced scan tools and multimeter testing to pinpoint electrical faults — from parasitic drains to intermittent wiring issues that other shops miss.
Battery testing, replacement, and charging system repairs. If your car won't start or the alternator is failing, we'll get it sorted fast.
Damaged, frayed, or corroded wiring? We repair and rewire harnesses, fix short circuits, and restore proper electrical continuity.
Flickering dash lights, blown fuses, faulty sensors, or exterior lighting failures — we diagnose and replace defective components.
Check engine lights, ECU troubleshooting, and module programming. We read codes, interpret data, and fix the root cause — not just the symptom.
Starter motor replacement, alternator repair, and ignition system diagnostics. No more clicking sounds or power loss while driving.
M and S Auto Electric is your dedicated automotive electrical shop right here in Baldwin Park. We specialize in the electrical and electronic systems that modern vehicles depend on — from simple battery replacements to complex computer diagnostics.
We know that electrical gremlins are the most frustrating kind of car problem. That's why we invest in proper diagnostic equipment and take the time to find the real issue, so you're not paying for guesswork.
We're not a chain shop. We're your neighbors who happen to be really good at making cars' electrical systems work again.
Electrical issues can be sneaky. We don't just swap parts and hope — we trace circuits, test components, and confirm the diagnosis before any work begins.
You'll know what's wrong and what it'll take to fix it before we lift a tool. No surprise charges, no inflated estimates, no pressure.
We use quality parts and proper techniques so the repair sticks. Our goal is to earn your repeat business, not your frustration.
