Electrical symptoms GM can diagnose
Common concerns include slow or no starting, battery warning lights, charging faults, fuse or wiring faults, scanner fault codes, sensors, blower problems and A/C electrical issues. A diagnostic process helps distinguish the actual cause from a symptom.
Inspection before estimate
Electrical repair pricing varies with the vehicle, component condition and parts needed. GM follows Inspect → Diagnose → Explain → Quote → Repair after approval.

Request electrical diagnosis
Four steps, in this order, every time
Diagnosis-first is the whole method: measure, write it down, then price it. It is also why every job, gas filling included, is quoted in writing after the checkup.
We test before we quote
The free 30-point A/C and electrical checkup runs first, about 15 minutes, with a written report of what was measured.
You get the estimate in writing
The report says what was found. Gas filling, like everything else, is quoted in writing after the checkup, and nothing starts until you approve it.
No work starts until you approve
Nothing is opened up or replaced before you say yes to the estimate. If the diagnosis changes the scope, you hear about it first.
Repaired, then checked again
The approved work is done and the car is checked again before handover.
