Mechanical Repairs & Computer Diagnostics
Modern commercial vehicles are equipped with complex electronic control systems that manage engine performance, transmission, brakes, and emissions. When a warning light appears or your truck starts acting up, guessing the problem can be expensive and dangerous. That is why All-N-1 Roadside Service uses advanced computer diagnostic tools to read fault codes and identify the exact root cause of mechanical issues.Our technicians are experienced with heavy-duty diesel and gas engines, as well as tr...
Modern commercial vehicles are equipped with complex electronic control systems that manage engine performance, transmission, brakes, and emissions. When a warning light appears or your truck starts acting up, guessing the problem can be expensive and dangerous. That is why All-N-1 Roadside Service uses advanced computer diagnostic tools to read fault codes and identify the exact root cause of mechanical issues.
Our technicians are experienced with heavy-duty diesel and gas engines, as well as transmission and drivetrain problems. We perform emergency mechanical repairs on the side of the road, at truck stops, or in your own yard. From alternator failures to cooling system leaks, we bring the parts and tools needed to complete many repairs immediately. If a repair requires a shop, we will be honest with you and help coordinate towing — but in most cases, we can fix you on-site.
We also provide periodic FMCSA inspections and brake adjustments as part of our mechanical services. By combining computer diagnostics with hands-on mechanical skill, we solve problems faster than traditional repair shops. For light-duty mechanical work on smaller commercial vehicles, our team is equally capable. Call us anytime — we are ready to diagnose and repair, 24/7 in the San Antonio region.
Electrical failures are often the hardest to diagnose, but they are also among the most critical for safety and compliance. At All-N-1 Roadside Service, we specialize in troubleshooting and repairing ABS (Anti-lock Braking System) faults, marker and clearance lights, and 7-way trailer connectors. Our mobile technicians carry multimeters, circuit testers, and a range of replacement components to fix most electrical issues on the spot.ABS problems can cause your trailer's brakes to lock up or fail...
Electrical failures are often the hardest to diagnose, but they are also among the most critical for safety and compliance. At All-N-1 Roadside Service, we specialize in troubleshooting and repairing ABS (Anti-lock Braking System) faults, marker and clearance lights, and 7-way trailer connectors. Our mobile technicians carry multimeters, circuit testers, and a range of replacement components to fix most electrical issues on the spot.
ABS problems can cause your trailer's brakes to lock up or fail entirely, creating a major safety hazard. We can read ABS fault codes and test wheel speed sensors, wiring harnesses, and electronic control units. For lighting issues, we repair broken marker lights, clearance lights, and tail lights to ensure your rig is visible and legal. A faulty 7-way connector is a common cause of intermittent brake and light failures — we clean, repair, or replace connectors as needed.
We also handle wiring for liftgates, refrigeration units, and auxiliary systems. Electrical repairs are performed meticulously to prevent future failures. Because we work 24/7 in the San Antonio area, you never have to park a truck with an electrical problem overnight. Our goal is to restore full function and safety so you can continue your route without delay or risk of citation.
