Anyone ever encounter this? Have an appointment this week but we all know that means it will be in the shop most of the summer with them not knowing how to fix it.
You most probably have a leak on top and around the front of the slide seal. This is an easily replaced seal when the slide is out, so look for a crimp or tear in this seal. If the seal feels soft and looks good, you could move the slide in and install the slide lock in the front and secure it. Then spray water at the front edge of the slide and onto the roof and let it run down on top of the slide. You also need to spray water under the slide cover. If there is no water inside the remove the slide lock and repeat a looking for water leaks. It would not likely come from under the slide because there is little spray there when driving.
