08 endeavor AC drain
very hard to find; there is a hole in the firewall behind where 3 or 4 small steel tubings turn from horizontal to vertical. problem is, you could do some damage if you probe too hard into this hole. better idea: i took mine to the dealer - there is a TSB (tech service bullitin) for the AC not draining. apparently, the gasket material they used at the factory deteriorates & clogs the drain. ask them to look for the TSB. otherwise, it is an 8 hour job, removing the dash & taking apart the evaporator housing. the recall replaces the gasket material with something that wont deteriorate. they did my truck under warranty.
