Replace Mazda Protege Power Window Regulator

Change Mazda Protege Power Window RegulatorOne problem I’ve had with my Mazda Protege is that Mazda decided to use cheap plastic in their design for automatic door locks, door handles and window regulators. In fact I’ve had to replace the driver side, front window regulator twice, the driver side, rear locking mechanism twice, the passenger side, rear locking mechanism once and the drivers side, front interior door handle once. Perhaps it’s not so much cheap as it is poor engineering, after all Southern Arizona does average over 100° for several months in the summer – not a good compliment to plastic.

Whatever the reason, when the drivers side window regulator went out again on my 2003 Mazda Protege I was faced with a decision:

  • Take the car into the Mazda Dealer and have them repair the window regulator
  • Order a new power window regulator and replace it myself

After weighing the cost in wasted time with the dealer and the remaining length of my extended warranty I decided to do it myself. I figured I’d be repairing the windows again in a few years so might as well learn how now; I’ve already had to have the dealer fix two power locks and three power window regulators on this vehicle.

The first step was to get the part. I was impatient, so I way over paid by picking up the power window regulator from the dealer. Ironically just purchasing the part from the parts counter took over an hour. It was also shocking to see that for $160 the window regulator didn’t even come with a motor!

If I had been a bit more patient, I could have ordered the replacement power window regulator with motor for my 2003 Mazda Protege from Amazon for a little as $62 but the idea of driving around Tucson without being able to roll up or even close my drivers side window wasn’t an appealing proposition.

This tutorial is for the 2003 Mazda Protege drvivers side, front Power Window Regulator. The Passenger side is similar, but this tutorial will be more or less useless for the rear doors.

Replace Mazda Power Window RegulatorStep 1 – The most obvious, open your Protege’s door. There is no need to disconnect the battery cables but you may want to turn off the cabin lights if they are set to turn on when doors are opened.
