MaybeYou may have it on "auto" not off check all switches off

You may have a faulty selector switch. Also some vehicles always blow heat even with the heater off.

Ihave a 1998 ford pickup it blow warm air from my heater I chang thwrmostat it still blows warm air?

The thermostat is not the issue. The thermostat regulates the engine temperature, but not the heater core temperature. There is a valve going to the heater core that is not closing all the way. It may be broken, clogged, or not actuating.

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.

I would expect a plugged heater core.Take your hand and feel the two heater hoses that pass thru the firewall on the passenger side; if one is hot and the other is much cooler, than you heater core is plugged and needs replacement.

Sounds like you have an internal heater box issue. Possibly one on the mode door motors quit or you have a broken door inside heater box. To access heater box, you have to remove entire dashboard assembly. This is not too simple of a task.

What is wrong when the ac and heater stops working but the blower still blows?

The AC and heater are completely different subsystems. The heater relies on heat generated by the engine and circulated by the engine coolant (radiator fluid) while the AC uses a belt driven compressor and separate fluids. Their only normal commonalities are the blower motor (which you said works), the ducting and the control head.

On 1991 Mercedes 190E When you try to regulate temperature using knobs it does not provide heat or cool air Replaced heater core and it still does not work Blower works?

To confirm your problem, the fan blows air but it is not heated?? I am not sure if there is a heater core in this car. The heat is generated in the engine and is transfered by a series of water pipes to a heating element(radiator) under the dash-board, the fan blows air over this radiator, it heats up and blows into the car. Things to check 1. see if the mechanical links between the temp. switches and the valves which control the flow of hot water into the radiator are functional.
