    I have a 2000 jaguar s type and I have no heat and was told it was the blend motor, the labor to fix is more than the part. Is this something that can be done without taking it to jaguar?

Using jumper wires, disconnect the plug where the blower motor is connected. Apply current directly to the positive in the plug from the battery or a fuse. Be careful which fuse is used. prefferably the fuse to the cigarette lighter. If not directly from the battery. it should run smoothly and at a good speed if it's good. if not it will have to be replaced.

Last week I ran the air conditioning unit in my 2006 Pontiac Torrent, when I got home the weather had turned cold so I put it back on the heat, however, the heater does not work now, all it does is blow...

Hello first of all

Your blend door motor / acuator is bad its basiclly a door that opens and closes when you flip your
heat to ac dial to either allow the hot air through the vents or cold air.

That being said on some suv and cars and trucks you can replace the motor that controlls this blend door can be changed without removing the dash and some you haveto remove the dash.

The blend door is located right by the heater core in the dash but sometimes the motor that controlls the door blend door is accsesable without dash removal and sometimes it is. I posted a picture below of what part is bad i hope it helps you.

If it helps please leave me 4 thumbs up thanks

The heater isnt working, I heard a clicking sound coming from behind the dash board and now it only blows cold air...

The noise you are hearing is the blend door motor. It is a DC motor that moves a door in the heater box that controls the temperature of the air coming out of the box. There are two typical possiblities, one, the blend door motor is bad and two, the blend door is broken and the motor cannot move it.

How do you fix cold air blowing from the heater when you are driving the truck.

Do you mean that the heater blows hot air until you start off driving? If so, then you need to check your blend door, it is probably broken, it is not really easy to change, it requires removing the entire dash. At the center bottom of your dash you will find a plastic cover, remove it and look in the center you will find a stepping motor, probably white in color, it will have an electrical plug in it, this motor controls the blend door. Remove three screws and remove the motor, then hook it up again and turn your temperature control from cold to hot, does the motor move? If it does then check the drive on the blend door (where the motor goes) can you rotate the blend door itself, if not the door is broken. The R&R procedure is extensive for the blend door. I would recommend a good shop in your area for repair of this door, but the test to determine that the door is broken is fairly simple. Hope this helps, let me know.

Why want the heater switch from cold to hot

this problem is caused by a defective air temperature control blend door motor/actuator failing, this little motor moves a door deep inside the dash to either supply ho or cold air or a mix of the two air streams, hence the name "blend" door motor. to replace the part u must remove the dash assembly.

The problem is in the heater box. To be more specific, the blend door. Check blend door operation and blend door motor. Located right side under dash. Remove blend door motor, with vehicle running, move switch from panel to defog and see if blend door motor moves.

Hot air blowing in car

sounds like your blend door motor has gone bad. this motor controls the blend door in the heater box that allows eather cold or hot air to flow or a mixture of both. replacing this motor is a big job cause the dash must be moved out to get to the motor.

2003 Toyota Echo heat not working. Fan, but no heat.

There is a valve on one of the heater hoses that allows heated water to flow through the heater core when you select heat. With heat selected and car warmed up check to see if both of the hoses feel warm. If not then water is not flowing through heater core and valve may need replaced or heater core is stopped up.

The clicking is the air temperature blend door motor, most likely the motor will have to be replaced the blend door checked to make sure it moves freely, this repair requires the removal of the dash assembly.
