Question about Volkswagen Polo
Is it leaking or just blocked? If it is blocked then under the bonnet (hood) locate the rubber heater tubes that feed through the bulk head. When you run the engine and select 'hot' inside the car check out which of the two rubber hoses gets warm first, this is the inlet pipe and the other, logically, is the outlet pipe. Disconnect both pipes from the engine and connect a high pressure (mains pressure on the garden hose may be enough) hose to the outlet (not the inlet). Back flush with full force making sure the waste from the inlet hose is collected in a suitably large bucket. It contains anti freeze which has a sweet taste but is bad for pets and wild life so it is important to collect it and dispose of it properly at your recycling center. After a little while it will run clear and you can let this drain away as this is just water flushing through. Reconnect the hoses and refill the coolant reservoir with antifreeze mix. Start the engine and allow the coolant to circulate and occasionally squeeze the rubber hoses to remove air blocks. Back flushing a heater core is a DIY job If the heater unit is actually leaking into the cars foot-wells then you will have remove the dash board and this is a pain. A neat trick is to have masking tape with you as you remove screws and to tape the screw along side the hole from which it has been removed. This avoids loosing screws and highlights those that need to be put back when reassembling. The air vents conceal dash screws so you will have to prise these out. Apply a screw driver tip to the center point on one side, press in and lever out. With the vents out you will see the dash screws behind. With these removed you will be able to remove the vent recess panels and this should allow you to see how the main dash assembly is fixed in the car. The main obstacles will be the instrument panels and switches. If the heater is leaking it might be best to entrust the replacement to the dealer as they will not damage anything. If you feel adventurous invest in a Haynes workshop manual and look up dash disassembly videos on Youtube. Good luck

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.
