If you have automatic climate control, you need to replace your blower controle module
If you have manual climate controls, you need to replace the blower motor resistor assembly.

My front defroster does not work but the back heater works.. if the van is running it will heat up but when you start driving the gage goes back to cold it blows cold but defroster wont work at all


Change the thermostat. Follow the top radiator hose to the engine. There is to T stat. That will get your heat back. on the defroster, it doesn't blow out air? doesn't switch vents? or just not get hot? Year make and model please.

Defrost and floor heat broke


Are you saying you don't have blower at all? Defrost, floor and panel are the only three separate modes you have. If it's not blowing at all and the fuses are good, check the wiring behind the glove box. There's a two wire plug with a large red wire just about center of the glove box opening that's known for burning out. If it is you'll see the burned spot on the connector or wont be able to disconnect it.

Heat and Air only blow on defrost and floor


The blend doors are controlled by small electric motors.
One of the motors could have failed, or the blend door is sticking.

My a/c will only blow out the defrost in a 97 gmc jimmy


It is either the servo door could be blocked by something like a pencil falling through or something falling and blocking it from opening. Or it is actually broken. I have seen them both ways. Mine was actually broken in my Ford F250. You should still take it in to someone who can deal with it for you.

No heat jaguar 88 xj6 fan wont turn on cool air out the defrost vent


I have the similar problem with both my Jaguars, one is a 1988 Jaguar XJS, the other is a 1987 Jaguar XJ6, both blow COLD air out some vents while it blows warm air for heat. I heard it had something to do with the cold air blowing as a dehumidifier, I don't know if this is true, but it is really annoying to have both cold and warm air blowing when I need heat in these cold Canadian winters. If you find out please drop this website a note and let us know how you solved it. thanks.
