Tried two other shops before coming here. Chapman diagnosed the issue in a fraction of the time and the fix held. Won't go anywhere else.

How long does Electrical Diagnostics take?
Most Electrical Diagnostics jobs are completed in 1–6 hrs. We'll give you a precise time estimate when you book. Complex cases may require additional time — we'll always call before going over scope.
What does the price include?
Our "diagnostic fee from" price of $145 covers all standard labor. Parts are quoted separately based on your specific vehicle. We share the full cost breakdown before any work starts.
Do I need an appointment?
Booking online takes under 2 minutes and guarantees your bay. Walk-ins are welcome but same-day slots fill quickly. We recommend reserving 24–48 hrs in advance for complex services.
Is there a warranty?
Yes. All labor is covered by our up to 4-year / 48,000 km warranty. If the same issue returns within the warranty period, we fix it free — no paperwork, no argument.
Do you work on all makes and models?
We service all domestic and import vehicles — American, European, and Asian makes. Our OBD-II tooling covers every model year from 1996 onward.
What happens if you find additional issues?
We call or text you with a clear explanation and a separate quote before touching anything outside the original scope. You decide — no surprises at checkout.
