    Do you mean a VALVE in the TEMP Control apparatus? My heater core is fine, but only cold air blows on the passenger side.

As snowbird said, it's most likely your passenger climate control system. Could be a short in a wire or a burnt acuator that moves the passenger door open and close. If you don't have the money or time to troubleshoot the problem you can pull down the glovebox and you'll see a metal rod about 8 inches long connected to the acuator. If you pop it off by the white connector, you can move it to full hot or cold. If it was the heater core it wouldn't matter where the air is comming out, it'd be the same temp.

It'll take you 5 minutes tops to simply check it by moving that door.

Good Luck

    Passenger side climate control may have a burnt out actuator, happened on my 95 park avenue. If you pull your glove box down past it's stops it's right behind it. Also if you're low on cash or time you can easily pop off the bar (6" thin metal rod) from the white connector on the actuator and move the blend door to full cold or hot. Sure annoying if you need to go cold or hot often but if you're strapped for cash it's a easy fix. It'll take ya 1 minute tops.

    Good Luck

Good for the summer not so good for the winter. Do you have auto climate control. That's the one that you can set your side hotter or colder then the other side of the vehicle. If this is the case then it could be the oh I can't think of the correct name of it but all it is, is an value with in the temp control. Or the other thing that it could be is the your heater core is gone. A good way to check this is to get the car up to operating temp fine were your inlet and outlet hose are for the heater turn on you heater with the controls in the high temp. Then touch the inlet hose that will be hot then touch the outlet hose that should be hot also, if not hot then the core requires replacement or you can try an coolant flush first to see if that works.

I have the same problem on my 99 park. I had it fixed two years ago ($300), but its doing it again. They said it was the "switch" that controled the blend doors. When I went back to the shop, they said the part was only warranted for 90 days. I'm going to a junkyard and get a used temperature actuator and put that one on. Don't have $200 for the part thats only going to last a year and a half..

02Park Ave is blowing warm air on passenger side, but not drivers side nor windshield or heater

Are you able to control the driver side air temperature at the dash registers? If not and you can control the passenger side of the dual climate system then you have an issue with the air temperature control door (moves between the heater core heated air and the AC evaporator cold air stream) deep inside the dash or the electric actuator that moves it or in most cases both.
