The Measure Of A Workshop – Or How To Find A New Home For Your Car

By | March 3rd, 2016|Case Studies|Comments Off on The Measure Of A Workshop – Or How To Find A New Home For Your Car

To Start
For sometime now I’ve been involved with other shops, either in a consulting, or in an industry 20 Group. Over the years I’ve developed a set of criteria that I’ve shared with friends and family about how to properly evaluate where to obtain high quality, ethical auto service. These apply if your auto is an Audi, BMW, Mercedes, Lexus, Saab, Volvo or VW.

Some of these items may seem basic, even commonsense, but all too often folks make the decision of where to take the car under duress, you want to have an ongoing relationship with shop before problems occur, […]

When Your Turn Signal Indicator Blinks Rapidly, Change Your Bulb

By | May 13th, 2015|Case Studies|Comments Off on When Your Turn Signal Indicator Blinks Rapidly, Change Your Bulb

However, most vehicles have a subtle way of letting you know when one of your blinkers burns out: the indicator in your dashboard will blink faster than normal.

The indicator inside your car is designed to operate under a specific electrical resistance. When the bulb burns out, the resistance changes, which causes the turn indicator in your dashboard to blink faster. This is a quick way to know whether your light needs to be changed without getting out of your car.
