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.

sounds like the drivers temp door actuator is not working should be located on the drivers side of the air box down by the gas pedal or center dash area.

this doesnt sound like a thermostat problem, rather a restricted heater core.
The thermostat housing, however, is a cheap cross-your-fingers-fix, and can be located by tracing the upper radiator hose back to the engine. The housing the hose is clamped to is where the thermostat is located. Remove 2 bolts, and replace thermostat.

The radiator is in the front of the car under the hood behind the grille. It will be rectangular shaped and have a fan set to blow against it. It will have a cap on the top. DO NOT REMOVE THE CAP WHILE THE ENGINE IS HOT. Beside the radiator is another rectangular shaped item that looks like the radiator but is the condensor for the air conditioner. It does not have a cap on top and is in front of the radiator.
The drain for the radiator is on the lower part. After draining be sure to close the drain before refilling.
Refill the overflow bottle as well.
AFTER you refill, let the engine run for about a minute while topping off the radiator so any air will work out of the system.
Then install and tighten radiator cap.
When you drain the radiator, dispose of the fluid according to local regulations or recycling center. Do not allow animals to drink any of it. It's poisonous.
You can get an auto repair manual from library, auto parts stores or the internet.
