How can i fix my Renault Grand Espace mark iv, poor heating system? The car takes ages to blow hot air when cold. You have to wait several miles before the engine is warm before the warm air starts to flow,not the most comfortable on a cold morning....any ideas??

if anybody has problem with heater not working at all just dash lighting up on 2.2 td try heater relay in fuse box left hand side of engine compartment purple relay with large red wire large brown small yellow and black wires attached to it if it clicks that does not mean its ok try another test on it
