I will be the owner of a 2011 TC. Van is immaculate with a couple scrapes on bumpers but not an issue. The issue i know the van is coming with is that the door switch does not lower or raise the front or rear windows. Cant control the power side mirrors and also cant fold them in either with the control. I did notice that i can open and close the vent windows all the way in the back. Would this point into the direction of needing a new door switch or am i looking at something bigger. All help will be appreciated
