What We Do
Wiring & Fuse Repair Done Right
Electrical problems are where most shops give up — or worse, start throwing parts at the car. Tracing a short circuit, open wire, or blown fuse through a modern vehicle's wiring harness takes patience, the right equipment, and real experience.
At Lynn's, we've been chasing automotive electrical faults since 1974. We use wiring diagrams, oscilloscopes, and targeted voltage drop testing to find the actual broken wire or bad connector — not just swap parts until the symptom goes away.
Common wiring jobs we handle: chafed harnesses from rodent damage, melted wires near exhaust, damaged trailer wiring, aftermarket installations gone wrong, and corroded connectors on BMW, Mercedes, Ford, GMC, Honda, Toyota — every platform has its weak spots, and we know where to look.

- An accessory (power window, radio, interior light) stops working
- Burning plastic smell from the dash or engine bay

Our Process
How We Fix It Right the First Time
Identify the Circuit
We pull factory wiring diagrams and trace which fuse protects the affected circuit, and what else shares that fuse. Shared-fuse failures narrow the search fast.
Locate the Fault
Using voltage drop testing, test lights, and continuity checks, we trace the circuit until we find the exact damaged section — not just swap modules in the hope it fixes the issue.
Repair to Factory Standard
We splice in new wire using heat-shrink crimp connectors or solder (per factory spec), protect the repair with loom or heat-shrink tubing, and test the entire circuit before we close it up.
Every Repair Backed by a 2-Year / 24,000-Mile
Nationwide Warranty
If anything we fix has an issue within 2 years or 24,000 miles of the repair date, we'll make it right — no matter where you are in the country. That's our commitment to every customer, on every repair, since 1974.
Questions from Downey Drivers
Frequently Asked Questions
Why does my fuse keep blowing?
A repeatedly blown fuse means there's a hard short somewhere on that circuit. Replacing the fuse without finding the short will blow the next one too — and can start a fire. We trace the circuit to find the actual damaged wire.
Do you repair rodent damage?
Yes — unfortunately very common in Southern California. Rats and squirrels chew through wiring insulation, especially on modern soy-based wire. We inspect the harness, repair the damaged sections, and can recommend protection measures to keep it from happening again.
Can you fix aftermarket wiring (stereo, alarm, lights)?
Absolutely. We regularly clean up aftermarket installations that were done poorly — improper splices, wrong gauge wire, missing fuses. We can also install new aftermarket equipment correctly.
Is wiring repair expensive?
It depends entirely on where the damage is and how accessible the harness is. A bad connector might be a 30-minute repair; a chewed harness buried under the intake is a longer job. We'll give you a clear quote after the diagnosis, not a vague estimate.
Is the repair warranted?
Yes — every wiring and fuse repair at Lynn's is backed by a 2-year / 24,000-mile nationwide warranty on parts and labor.
