SS Auto Garage provides truck trailer electrical services for commercial vehicles and fleets across Montreal and Saint-Laurent. Accurate fault detection, honest quotes, and reliable repairs from experienced technicians.
Problems We Solve
Electrical faults on commercial trucks and trailers are some of the most frustrating problems to deal with because they are not always obvious. A wiring issue can hide behind a dozen different symptoms before the real cause shows itself. Our technicians use proper electrical system diagnostics equipment to find the source fast and fix it correctly the first time. Here is what we regularly deal with:

OUR SERVICES
We offer a complete range of truck trailer electrical services in Montreal for commercial vehicles, covering everything from simple wiring fixes to complex electrical system diagnostics and repairs.
Electrical problems on commercial trucks and trailers rarely announce exactly where they are. Our electrical fault diagnostics process uses proper testing equipment to work through the system methodically, identify fault locations accurately, and confirm the fix is complete through performance testing before the vehicle is returned to service.
Damaged wiring on a commercial trailer causes problems that ripple through multiple systems at once. We handle trailer lighting repair, trailer wiring harness repair, and short circuit fixes on all trailer types. Every wiring repair is done cleanly and tested fully before your trailer leaves our shop and gets back on the road.
Faulty sensors feed your truck’s systems incorrect information and that leads to poor performance, fault codes, and unreliable operation. We handle sensor troubleshooting to locate the exact fault, carry out fault resolution to correct it properly, and verify performance restoration and system accuracy improvements through testing before your vehicle is cleared for use.
Brake light and electrical brake system faults are among the most inspection-critical issues on any commercial trailer. We carry out brake light diagnostics to find the exact fault location, complete all required sensor repairs to restore proper function, and run safety performance checks to confirm your brake electrical system is fully operational before your trailer goes anywhere.
The ECM controls critical engine and system functions on your commercial truck. When it develops a fault, performance suffers across the board. We use proper electrical system diagnostics tools for accurate fault detection, carry out system recalibration to restore correct operation, and verify performance restoration through testing so your truck runs the way it should again.
A commercial truck with an unreliable power system is a breakdown waiting to happen. We carry out battery diagnostics to assess charge capacity and health, handle charging system repair including semi truck alternator repair and truck starter repair, and make power reliability improvements so your truck starts and runs without electrical surprises.
