Torque converter repair service near Anoka, MN

I took my college students car to Lake Elmo repair for an oil change and a headlight being out. I told the tech that the headlamp was brand new (and retested in the other headlamp) and that the problem had to be in the wiring harness. The total charge was $165. It appears they simply replugged the light in. My student told me 2 days later the “oil change” alert was still on and that the headlight was out (again). I had him take the car back to Lake Elmo Repair and they told him he would need to bring it back with an appointment. I don’t think it is fair to expect us to have to come back according to their schedule when the problem was the poor workmanship of Lake Elmo Repair. I figured the convenience of this shop would be worth it - but it’s not. I’m going back to Myron’s
