The Trailer Shop St. George Doesn't Have Enough Of
Try calling around St. George with a bad trailer axle or a cracked leaf spring and you'll see what we mean — most shops simply don't do trailer work. We do. Whether you're hauling a livestock trailer out toward Hurricane, pulling a utility trailer for a side job, or towing a travel trailer up to Pine Valley for the weekend, we can get under it and fix what's actually wrong.
We see a lot of wear-and-tear damage from washboard dirt roads and the heat cycling that comes with Southern Utah summers — bearings that need repacking more often than people think, wiring that corrodes faster than you'd expect, springs that sag after one too many loaded trips.

Trailer Wiring (Lights & Brakes) in St. George, UT
Trailer Wiring Repair in St. George, UT | Prime Tire & Auto Repair
Trailer lights out or brakes not engaging? We diagnose and repair trailer wiring in St. George, UT. Call 435-414-3883.
Trailer Wiring for Lights and Brakes
A trailer with a brake light out or brakes that aren't engaging properly is more than an inconvenience — it's a real safety and legal issue, especially towing on the highway. We trace and repair wiring for trailer lights, turn signals, and electric brakes, and we test the connection at the hitch to make sure it's actually working, not just plugged in.
Corrosion is the usual culprit out here. Connectors sit exposed to dust, heat, and the occasional flash flood puddle, and that combination eats through wiring faster than people expect. We clean up corroded grounds and connectors rather than just patching over the symptom.
If your trailer's lights work sometimes but not always, that's a wiring problem worth chasing down now, before it leaves you without brake lights at the worst possible moment.

Frequently Asked Questions
Why do my trailer lights work sometimes but not other times?
That's a classic sign of a corroded connector or ground, often at the hitch connection point. Intermittent contact causes inconsistent operation.
Can you test whether my trailer brakes are actually working, not just connected?
Yes, we test actual function, not just that the connector is plugged in.
How long does trailer wiring repair take?
Often same-day, though tracing an elusive intermittent issue can take longer.
What usually causes trailer wiring problems out here?
Corrosion from dust, heat, and occasional flash flood water exposure at connectors and grounds.
Is it legal to tow with a broken brake light on the trailer?
No, that's typically a violation and a real safety risk, especially towing on the highway.
Can I just run new wire instead of tracing the old problem?
Sometimes that's the right call if the existing wiring is too degraded, but we'll diagnose first rather than automatically rewiring everything.
How much does trailer wiring repair cost?
It depends on the scope of the issue. A simple connector fix is inexpensive; a full rewire costs more. We'll diagnose first.
Will you check my tow vehicle's wiring too, or just the trailer's?
We check both sides of the connection since the issue can originate at either end.
