My 2000 Venture's rear vent windows (adjacent to the third row seats) have stopped working. I tested the fuses that are denoted as "PWR QTR VENT" and "CAN VENT SOL" with a multimeter, and they were OK. What should I look at next?

 

Are you talking about the power ones, if so they may have just stopped working, you might need to get some new ones to put in.

 

on the passenger side front floor under plastic sill and carpet there is a bunch of wire untape them look for 3 orange and a grey- I think. They need to be tied together. Just solder them. Seen that 3 times now
