You have a 1988 sunbird the driverside floorboard stays wet you have heard this a chronic problem with these vehicles any ideas on what would cause this?

Sounds like the heater core is leaking to me. Take off the kick panels underneath the dash and look up. if you see coolant dripping from the housing, then you got your culprit. Not likely. What you heard about this being a chronic problem is right, these cars are very leaky for water. The problem is either the door seals or windheild seals, both leak. Find them and seal them. (This may be harder than it sounds.) I wrote a post on this in another Sunbird question. Look for posts about sunbird and leaks, you'll find it.
