Tomcat3 answered as above. The fuses are most likely under the dash behind a small panel that will pull out to expose them. Check the passenger side and drivers side. Mine are on the dirvers side but then I have a lhd mk. 3.

I've got a different tack.
First pop the lid and check that hoses to and from the heater matrix are actually connected through the bulkhead. The matrix often leaks at about ten years of age due to cracking O-rings in its top cover; this is a dash-out job to repair or replace. As you might imagine, the quick and dirty fix is to bypass the heater by joining the two hoses on the engine side of the bulkhead.
If it all looks present and unmolested (and no smell of antifreeze in the carpet) remove the felt panel above the passenger's toes. Look under to the left, for the round base of the blower fan. You'll see a maroon/brown plug with four wires in it - two are large, two thin. Unplug this and with the motor running, use a test light to see if there's 12V at the large red wire in this plug. If so, you have a controller fault.
If there is not 12V at the fat red wire, you have a supply problem - on pre multiplex cars (and being a 51 plate yours might be either type) Fuse 29 is officially the supply line but wiring books are not always bang on. The current passes from the battery/ignition switch through the fuse panel, to a black relay under the dash, then to the four way plug. On multiplex cars, I can't comment as the wiring for them is quite different.
Anyway, hope this gets you moving towards a solution.
Thanks addo..im off to work now but hopefukly try this later this afternoon when home..gotta start somewhere..oh there is heat blowing out but only when I drive at high speeds as its being pushed through..
It's likely to be your heater resister pack that needs replacing.
Give the motor a thump, see if it starts going, mine did it and I managed to keep it going by walloping it for a few weeks untill I got a new motor.
Somedays you're the pigeon, Somedays you're the statue.
Guys ive just been out to it and first thing i did was tap the blower under the glove box gently with a hammer...soft tho.. and its started to work on all speeds as it should..
So whats likely to be wrong and will it go again lol?
