Autronix is a professional auto electrical service built on one simple rule: your car should be reliable every single time you turn the key.
Mission & Values
Modern vehicles are basically computers on wheels. When something goes wrong — the battery keeps dying, the dashboard lights up like a warning panel, the A/C controls stop responding, locks or windows quit, headlights flicker, the car won’t start for no clear reason — most shops start guessing. They swap random parts, clear codes, and tell you “try it now.” Sometimes it works. Most of the time, the problem returns.
We don’t work like that.

We specialize only in the electrical and electronic systems of the vehicle: power delivery, wiring, sensors, control units, relays, starting and charging systems, lighting, comfort systems, signal networks between modules. This is the part of the car that a lot of mechanics avoid and a lot of owners don’t fully understand — and it’s exactly what we’re built for.

We handle the problems that are “hard to find,” “intermittent,” “comes and goes,” “nobody else could figure it out,” or “it just randomly dies at night and then won’t start in the morning.” That is our zone.
Electrical Repair & Diagnostics
Instead of throwing random parts at the car, we test first. We scan, measure, trace voltage drop, check continuity, isolate shorts, and confirm why something failed. Then we fix that exact issue — bad ground, damaged harness, failing relay, weak alternator, unstable module, etc. That means less cost, less downtime, and no repeat of the same issue next week.
  • We perform in-depth testing to find the real cause of electrical problems.
    Full Electrical Diagnostics
    That includes scan tool fault reading, live data analysis, voltage drop testing, continuity checks, communication line testing, parasitic draw testing, and component-level inspection. Translation: we don’t randomly replace parts. We confirm the fault before we repair.
  • If your car struggles to start, loses power in cold weather, or dies overnight, the issue could be the battery — or not.
    Battery Testing & Replacement
    We test state of health, charging ability, and load performance before replacing anything. If a new battery is needed, we install the correct type for your vehicle and make sure it’s charging properly.
  • The alternator keeps your battery alive.
    Alternator & Charging System Repair
    If it’s weak, failing, or not regulated correctly, you’ll get dim lights, strange electronic behavior, and eventually a dead car. We test alternators, voltage regulators, wiring to and from the charging system, and replace or repair components to restore proper charging.
  • Turn the key and nothing? Click but no crank? Intermittent start?
    Starter Motor & No-Start Issues
    We diagnose starter motors, ignition switches, relays, fuses, and wiring to identify why the engine won’t turn over. We also check for immobilizer or security system interference on vehicles with electronic anti-theft systems.
Why Choose Us
We solve the electrical problems other shops “couldn’t find.” We diagnose first, repair second — no guessing, no throwing random parts at your car and charging you for the experiment. You get clear explanation of what failed and why, in normal language. The result is a car that starts, charges, and runs the same way every day, not just on good days.
  • Accurate Diagnostics First
    We don’t just “change parts and hope.” We confirm the cause with the right testing, then repair exactly what’s wrong. This saves you money and stops the cycle of replacing random components that weren’t broken.
  • Experience with Modern Vehicle Electronics
    Today’s cars are controlled by computers, sensors, and communication networks. You can’t fix that with only mechanical experience. You need electrical knowledge. That’s where we specialize.
  • We Solve the “We Couldn’t Find Anything” Problems
    If other shops said “everything looks fine” but your car clearly isn’t fine — draining battery, flickering lights, warning lights at random — we’ll go deeper. Intermittent, hard-to-find electrical faults are exactly what we’re built for.
  • Clean, Safe Wiring Work
    Bad wiring can kill fuses, start fires, kill batteries, and mess with airbags and safety systems. We wire and route correctly, fuse correctly, insulate correctly, and leave your car safe. We fix bad aftermarket installs all the time for a reason.
