When it rains water runs into the engine compartment and all of my wiring is dripping water. The service manager told me that they see this problem a lot and that they don't know how to fix it. I have looked online and there are many people complaining about this. Most people think it is the cowl leaking on the bottom of the windshield. I feel like if my wiring gets wet enough that I will have a malfunction.
