Window leaks and other information
Posted: Tue Apr 26, 2022 7:53 pm
The original windows in our B190s were made by Hehr, which has been purchased by ParkIn Accessories.
The window design is ...interesting. There's a trough for the rain that can easily get clogged. If that happens, the trough can overflow and leak inside the van.
Having leaks from the Hehr windows?
Nuclear option: You can order new windows. Here's a list from someone on the Facebook group that did (I redacted the name and address for privacy). I believe, but am not certain, the order is:
I know I saw a post on the Facebook group where someone replaced them with another brand, but I can't find it now. The company gave them information on what sizes they needed, which the customer supplied and they made new windows for them. The radius on the corners is apparently pretty standard.
Resealing them: Note that like any hole in an RV, it can leak for the regular reasons, too - i.e., the sealant has failed. In some extreme cases, you might even entirely remove the window, clean the fiberglass, and reinstall it. I haven't done it, but basically you need to remove the Phillips screws on the inside and push the window out - you'll probably have to cut the sealant. Use acetone to clean the old adhesive off the fiberglass and the window frame. Use new butyl tape and sealant to reinstall the window.
Other thoughts: Some people have installed stick-on rain gutters, like this.
Upper front window: This thread has directions for replacing it.

Having leaks from the Hehr windows?
- Directions for refurbishing the windows.
- Here's a note about cleaning the drains that might help. (note this is a post in the same thread as the previous link)
- Some suggestions for cleaning and refurbing them.

- The first one is the window above the sink
- The second one is the bunk curb side
- The third one is the bunk street side
- The fourth one is the couch window
