Why diagnose before replacing parts

A warning light says something is wrong, not what. Finding the cause first helps avoid replacing parts that were fine.

What to tell us

Which lights are on, and when they came on
What the vehicle is doing differently
Whether it runs, and whether it is safe to drive

How it works

Call or text: tell us the truck or trailer, what it is doing and where it is
We come to you with the tools to work on it where it sits
Back on the road. Most common roadside problems can be repaired on site. We do not tow
