Quirky Electronics
I disconnected the battery, turned on my headlights to drain all residual juice in the lines and reconnected the battery. After I did this, the pneumatic door works again, but the windows delay after the door is shut. Is this just a quirk, or a bigger problem?
It had to do with a module under the rear seat.
This module controls the window function.
Mine is starting to do the same trick again.
It seemed to go away with the new battery last spring.
I also think that it can cause a battery drain.
Thats what I am getting again too. After 4 days
sitting, battery is down to like 11 Volts and just enough to
start the car. And the windows are getting worse and worse
about sealing up the first time. Especially with a low battery charge.
Sounded like it was in the trunk but not sure. Trunk closes fine and so does passenger door but drivers soft close is out and hear air leaking from door.
