Power Window Repair Tampa Ford Expedition, Lincoln Navigator 2003-. I had a 2003 Expedition 4.6 (447,000 miles before it finally died). The windows on this truck use a cable regulator. It’s a huge assembly and takes up about 25% of the door. It does not include the motor. The motors are seldom the problem. If your window is running slow you might try LIGHTLY spraying the 2 up and down run channels with any silicone spray. They often dry out from the heat and cause the glass to grab. DO NOT spray the horizontal seal strip (the channel your arm would rest on if the window were open.
If the window does not make any sound it is probably the switch. If you can hear a click in the door when you press the switch down but nothing, when you press the switch up it, is probably the 5-button switch.
If you hear a crunching, grinding sound, OR, your window goes up VERY slowly it is usually the regulator that needs to be replaced. Changing it is a major piece of work.
This would be a good time to call Power Up Auto @ 727/410-9995.
