Water is getting into my trunk through the seals around the tail lights. Are these seals easy to replace? Thanks. Ted -- If it keeps up, man will atrophy all his limbs but the push-button finger. - Frank Lloyd Wright
Yes. These gaskets may be bought online. The alternative is to diassemble the tail light, clean the old gasket, and caulk with silicone.
A few years ago I ordered bumper parts and a main relay from one or two of these, but with good results. I price-shop at all of them a lot, though. http://www.honda-auto-parts-wholesale.com/ (perhaps the best prices plus free shipping) http://www.hondaautomotiveparts.com/home.htm (great drawings, even if you don't buy here) Taillight gaskets for a 91 Accord go for under $5 each here. http://www.hparts.com/part.html (web site not as user friendly when searching for parts)
You should take your car immediately to a dealer. They are the only ones who are experienced enough to be able to deal with this problem.
