Skylark Automatic Passenger Window
A couple summers ago I was driving a 1996 Buick Skylark. Unfortunately it’s air conditioning was broken, so since it was hot out, I would immediately roll down both front windows when I got in the car. I’m kind of impatient, and the passenger side window was really slow. I got tired of holding the button down for a good 8 seconds every time I got in the car, so I decided I’d add an automatic down button just like the driver side window had.
I took out the window control unit, added a relay and a 555 circuit set to run for about 9 seconds to the control unit, a second relay to move the driver auto down button for convenience, and the two buttons.
It worked pretty well for the rest of the time I had the car. Only problem is that it would sometimes trigger accidentally when the car was turned on. I added a bit to the circuit that really cut down on this, but it still happened rarely. I eventually had to replace both front window motors because they stopped working due to age (which is also why the passenger window was slow in the first place).
