1994 Plymouth Voyager mileage: 89,000. Would too much antifreeze cause my vehicle to blow cool air from my heater? It works fine when in park, but it and the car cool down when driving. The needle goes back to cool also.

Too much anti-freeze would not cause cool air to blow from your heater. Your problem is probably with the engine thermostat; it is either stuck open or it is too cold (160 ) and should be replaced with the proper one.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
