If the heater fan is working then either the heater direction vent is stuck in the closed position or the heater matrix has a blockage , the vent is controlled by the direction control knob/slider, does this feel like it is moving as before the problem started,if not strip out the control panel and check if the control cable is still connected at both ends, if this is ok then i'd say there is a blockage in the heater matrix which is par of the engine's coolant system , if the engine isn't overheating etc then the matrix is most likely blocked,then i'dgo ahead and flush through the matrix by removing the top and bottom hose ,these will be 2 hoses that enter the interior of vehicle through the bulkhead access from engine comparment, probably around 1 inch/25mm in diameter , clamp these hoses shut before removing them as you dont want to loose all engine coolant , hose clamps are cheap and readily available , then undo the pipe clips and use a water hose with a nossle to flush out the matrix ,replace the hoses run engine and open close heat control ,cold to hot , a few times , run engine for around 10 minutes hopefully you will have heat ,let engine cool and check coolant level as will need a top up hope this helps
