Hello everyone on the forum.
Here’s a case I’d like to describe so others can avoid making the same mistake in the future:
A few days ago, I asked about sealing the cabin because hot air from the engine was excessively heating the driver and passenger during fast driving. I followed the advice to seal the gaps between the body and cabin panels with thick foam. Unfortunately, I went a bit too far and also pushed foam under the dashboard where it meets the windshield frame.
At first, everything was fine and comfortable—the hot air issue was gone—but then a new problem appeared. During rain, I noticed a lot of water pouring onto my left foot. Where was the water coming from? And I lost my turn signals.
When I got home, I discovered that there was a leak at the junction between the composite body and the windshield frame. Too much material had been removed from the composite, creating a hole that wasn’t properly sealed by the windshield cover. Water entered the cabin, and since there was foam there, it soaked it up like a sponge. The water overflowed onto my foot and, unfortunately, also onto the fuse panel, which is located nearby. The flasher relay for the turn signal burned out.
That’s the diagnosis and root cause. Avoid stuffing anything behind the dashboard. Now I need to figure out how to properly seal the windshield mount, and I’ll have to replace the module. For now, I swapped it with the one for the hazard lights.
Well, that’s the adventure.
Best regards!
