Common Vehicle Wiring Issues
Wiring problems can affect almost any system in your vehicle. We regularly diagnose and repair:
- Electrical shorts causing blown fuses or intermittent power loss
- Damaged or corroded wiring harnesses
- Rodent damage to wiring under the hood
- Wiring related to a parasitic battery drain
- Faulty connections causing flickering lights or gauges
- Aftermarket wiring installed incorrectly
Left undiagnosed, a wiring issue can cause repeat problems that keep coming back even after other repairs.

Vehicle Wiring FAQs
How do you find an electrical short?
We use diagnostic equipment to trace the circuit and pinpoint exactly where the short is occurring, rather than replacing wiring by trial and error.
Can rodents really damage my car's wiring?
Yes, rodents chewing through wiring under the hood is a common cause of electrical problems, especially on vehicles parked outside or unused for stretches of time.
Why does my electrical problem keep coming back?
A repair that doesn't address the actual damaged section of wiring, only the symptom, tends to resurface. A proper diagnosis finds the actual break or short instead of patching around it.
How much does vehicle wiring repair cost?
It depends on how much of the harness is affected and how accessible the damaged section is. We'll walk you through the cost before starting any work.
Can you rewire an aftermarket accessory that was installed wrong?
Yes, we can correct wiring for aftermarket accessories, stereos, or lighting that wasn't installed properly the first time.
Can a wiring issue drain my battery overnight?
Yes, a short or bad connection can create a parasitic draw that slowly drains the battery even when the vehicle is off, which is one of the more common wiring complaints we diagnose.
