Updated June 2026Automotive Electrical Repair in Aurora, CO
Modern cars run on electricity as much as gasoline. More than 30 computers and miles of wiring control everything from your engine to your door locks. When that system fails, the signs can be confusing: a car that won't start one morning, lights that flicker, a battery that keeps dying.
At Tune Tech Automotive, our ASE-certified mechanics have been finding and fixing electrical problems since 1978. We use pro-grade diagnostic tools to find the real cause instead of guessing at parts. Qualifying repairs are backed by the NAPA 24/24 nationwide warranty.

Colorado Climate TipAurora's temperature swings are hard on car batteries. Winter cold cuts a battery's cranking power, and summer heat speeds up wear inside it. In Colorado you get both, every year. If your battery is more than three years old, have it load-tested before the first cold snap instead of finding out in a parking lot.
