Ever wonder why today’s cars seem to have so many window regulator problems? Seem like you don’t remember replacing regulators in older cars? You are right to wonder. The old style regulators in BMW, Audi, Volkswagen, Mercedes, Volvo, were all a very heavy duty regulator. It used to be the only time we usually had to replace them was when someone was in an accident and it got damaged. They rarely failed from regular use. I don’t know who had the bright idea, but all the manufacturers switched to a new style regulator. Instead of the old regulator with large metal teeth that meshed with the window motor, they now have a very weak regulator that is cable operated with plastic pulleys. Most have updated them recently and are improved, but still no where near the strength of the old style. The good news is that most of the rest of the car is vastly improved and overall our vehicles today cost much less to operate. Feel free to e-mail any car questions to Thayne@IndImport.com.
