It makes me wonder why this would start fogging after so many years. I'd still suspect something is getting wet. Does your 88 have carpet? If so, just to be sure I'd check the padding in a few low lying areas. Any holes in the floor that you're not aware of? I hesitated to ask that question but your Ranger is 18 years old.

ok now tonight on the way home, even with the a/c on and the fan on high it never cleared the windshield! no rain in sight either? it must be the heater core? its putting heat out but i dont know what eles to try! the carpet is bone dry! maybe something blocking the heater hose? im gonna flush out the radiator and put in new antifreeze first! then i guess change out the core again! it will be easier this time since it was not to long ago i did it!

Make sure there's no water lying in the fresh air intake. There should be a drain hole on the bottom of the cab, it may be plugged, allowing moist air to be drawn into the system.

Git under there and look! It should be toward the front of the cab, right under where the intake is. Every vehicle has such a drainage system, or you'd have a pond in front of your windshield! I've never looked for mine bfore, but since I mentioned it, I better go have a look-see pretty soon or lady fortune will make it my problem too.

one thing that i have found that helps fogging is if you used RainX, you can get it at basically any local autoparts store. if you put it on the outside and the inside it helps repel rain, and on the inside helps fogging.

My folks have an 87 xcab. I borrowed it last winter while I was replacing the engine in my 88. Same deal, fogged windows, plenty of heat. I pulled the core and sure enough it had been leaking, but there was so much junk in the housing that no coolant could ever reach the floor. Replaced the core with the one out of my truck and WHALA no more fog. I have had cores go bad in two years, no wet floor but enough to make it impossible to see out without the window open, and in a snowstorm that aint fun.
My nickkle is on the heater core . . .

Most of us think you're on the right track. The last thing I was going to suggest was pulling the core, reconnect it while you have the hood up and run the engine. If there's a leak, you'll see it when it gets hot and the pressure builds up.

Easy- if the warm air has moisture in it. If you breathe on a window (warm air) and it fogs up. I'd be curious to see if the problem was better if you shut the fan off and opened a window. (I've never driven a Ranger that didn't fog up a bit with the fan off and windows shut.)
