Wow! I can't believe what I am seeing! I have owned two Ford Windstars, a 1998 and a 1999. I have replaced the transmissions in BOTH, and within a year they are both going bad again (one is totally shot!) the front end in the 1999 is banging and clanging around, and the electric wiring in both are messed up.
The heat kicks on high when ever it feels like it, the interior lights won't shut off, the horn quit working, etc... Apparently these are common problems with these vehicles.
I don't think I'll ever buy one of these again! At least I know it isn't just me or my driving!
