Our Senator Oklahoma is currently at the dealers for its first service and the dealer has just contacted me to say that they will need the van for a few days longer to replace the front window seals. Evidently the front windows on the Senator can cause the seal to flex which lets water gather around the lower catch on the two side windows. With the recent heavy rain they said this has just starting to happen with our van. Bailey have countered this by using a double edged seal on current build Senators which they are sending to fit on our van. It may be worth keeping an eye on your van or even asking the dealer to carry out this work at the service.
