My son just picked up a 1994 Integra LS. All looks good except I discovered water in the spare tire well. Thought it might have been a fluke so I dried everything up waiting for the next rain. Lastnight it poured big time and sure enough, there's water in the spare tire well again. It looks like the rain is running down the hatch opening sides and disappearing under the rear tail light panel findind it's way to the bottom. What can be the cause? Are there drain holes that might be plugged up? Or is there a seal somewhere inside the backend that might not be doing it's job ?
