Modern vehicles run dozens of control modules, miles of wiring, and hundreds of sensors — which means an electrical fault can show up as almost anything: a dead dash cluster, windows that quit, a battery that drains overnight, or a warning light with no obvious cause. I-70 Auto Service provides methodical electrical repair in Kansas City, MO that finds the actual fault instead of swapping parts.

Why It Matters

Our technicians work from wiring diagrams with lab scopes, multimeters, and factory-level scan tools. We test circuits under load, trace voltage drops across connectors and grounds, and isolate parasitic draws with current clamps. Corroded grounds, chafed harnesses, failed relays, and water-damaged connectors are everyday work for us.

Common Signs & Symptoms

We also handle the accessory side: power windows and locks, lighting and headlight upgrades, trailer wiring, aftermarket accessory installs, and module communication faults on CAN-bus networks. If a previous repair left a nest of splices behind, we'll clean it up properly with sealed, factory-style connections.
