check to see if u have antifreeze in the radiator or reservoir
If the problem is climate control on both temperature extremes it maybe the "blending door" mechanism. Usually if the mechanism fails you can hear it "flip" around during moderate acceleration (noise will occur from below the radio in the air flow housing). Ford models around the 1999/2000 years used this design and many owners had problems develop. I am unsure but I believe that it is very difficult to repair in that the entire dash has to be removed from the vehicle in order to make repairs.

Heat wont work in 1983 Chevy silverado?
Depends, Is it blowing air at all? If not then could be the fan, fan motor, or an electrical problem possibly with the heater controls. If it is just blowing cold then your going to want to check the heater coil, on that truck I believe it is on the passenger side under dash/floorboard. you may smell anti-freeze if so the heater coil is the problem.
In your truck when you switch from cold air to heat the air still blows cold?
Interior heat uses the engine heat. If the engine is still cold, the heater will blow cold. If the engine is warm and the heater is blowing cold, you have a problem with the heater. Check the water in the radiator and see if it is rusty. If it is rusty, change your coolant, thermostat, and hoses. Look at the heater hoses when someone steps down on the gas pedal. If a hose collapses, replace your heater hoses. Otherwise take it to a mechanic.
