Wenzel's Automotive in Winthrop Harbor diagnoses and repairs automotive electrical problems: starting and charging systems, wiring, fuses and relays, power windows and locks, and dash warning lights. We trace the fault with test equipment and wiring diagrams so the repair fixes the cause.

Salt, water and wiring
Road salt and slush work their way into connectors and ground points under the car and in the engine bay. Corrosion there causes the intermittent problems that are hardest to pin down: a gauge that drops out, a light that flickers, a window that works some days. Clean, tight connections fix many of them.
Testing before parts
Electrical repairs start with measurements. We check voltage, grounds and the circuit for the part involved, so you pay for the repair that solves the problem.
