PT Cruiser L4-2.4L Turbo VIN 8 (2005)
windows are fully up, the modules will lower the respective front window 40 mm, lower the respective rear window for 0.52 seconds (approx. 55 mm)
and the driver window module will ground the top up relay control circuit. Once the top is back up, the windows will not raise automatically. When the
top switch is pressed in either position, the driver window regulator module will ground the respective relay control circuit for a maximum of 30 seconds
. The window regulator module monitors vehicle speed and if the speed is over 15 mph the top will not operate.
POWER WINDOWS
The window switches are hard wired by a mux circuit to the respective window regulator module. The respective rear window motor is hard wired to the
module. The front window motor is directly attached to the module. Both front door window switches have the express down feature. The module will
cease lowering the front glass when a fully down position is sensed through the hall effect sensor. The module will cease lowering or raising the rear
glass when a high stall current is detected for more than 400 ms.
SMART GLASS
When a door is opened, the respective module will receive a signal from the door ajar switch or the window drop switch. The window drop switch is
directly controlled by both the interior and the exterior door handle switches. The drop switch is part of the door latch. This switch is faster than the door
ajar switch to signal an open door operation. At that point the module will drop the front door glass 10 mm. However, if the window drop switch should
fail, the door ajar sense would also drop the window 10 mm and the module would set a trouble code. If the module receives a door ajar switch open
(door closed) it would raise the window 10 mm. The module knows the position of the window by counting the motor rotation through the hall effect
sensor in the module. If a door window is raised while that door is open, the module will raise the glass up, but when the door is closed it will raise the
glass 10 mm further up.
When the convertible top down switch is pressed to the first detent, the input is received by the window regulator modules which will lower the door
windows approximately 40 mm, lower the rear window glass for approximately 0.52 seconds (approx. 55 mm), and after a 200 ms delay, energize the
power top down relay to lower the convertible top.
The window regulator module monitors ambient temperature from the engine control module. At cold temperatures the stall time for the rear window
motors is increased because of the possibility of ice or frost.
