Recently acquired 98 Coupe that had sat outside for years. In getting it back into shape I found all my udders were full of debris. I've read where they can cause all kind of problems if they get backed up. What would go bad if AI cut the ends off so they were open drains?
The utters are supposed to let water collect/drain, but hold back air flow.... If you cut the utters off you'll be blowing some of your air-conditioning & heat under the car.
Keep the utters and just clean them once in awhile
He is talking about the 90 degree HVAC DRAIN udder that fits on the end of the condensate drain tube on the passengers side of the fire wall.
The udders that you are discussing, only drain the windshield cowl. The HVAC Fan draws FRESH in air from that cowl area. The cowl area somewhat sealed from the engine bay. The collapsed ends of the udders, help prevent drawing any air in from the road or engine compartment.
IF,,,,, It were ME, I would just get into a habit of checking the drivers side udders each time you check your oil. The big one on the passengers side rarely clogs up and can be serviced when it needs it.
