I have no idea what will be 2nd on the list to fail if drain holes get clogged. At one point that cavity has to overflood if the clogging continues and it keeps raining  . Loads of other electric units in that area that can suffer damage; ULF, CD changer, speakers etc.
I wonder if the frequent clogging of those drain channels is due to that strange rubber grommet that sits on the underside of those channels. |
The rubber piece at the bottom of the drains is a one way valve to let water out and keep critters from coming back in. It doesn't help with the clogging issue for certain.
On pre-facelift cars that had the audio amp in the battery well, that's where the water collected when the drain funnels got clogged and overflowed. It killed the audio amp and the top motor. Post face lift the audio amp got moved to the passenger compartment rear bulkhead behind the carpet in the trunk. The other items that can get wet if the drains overflow are the top controller and the woofers. If one was really ignorant of what was going on in a pre-facelift car you could have water take out the top motor, the top controller, the audio amp, and both woofers. The cost to recover from that is mind boggling! Probably would be a figure that would lead one to scrap the car.
