I have just repaired the fan restistor on my Almera 1.4 Si "P" reg. Had a problem to find it at first, its actual located on the bottom of the heater box, behind the glove box, to the right of the fan motor housing, you will see the wiring loom going to 2 plugs, one plug goes to the fan motor, and the other plug goes to the resistor pack, the resistor actual goes inside the heat box, so the only thing you can see is the end plate where the loom plugs on, you will see 2 cross head screws holding the unit in place, once the unit is removed, after cleaning the dirt off it, you will see a blob of solder on the circuits near the top, check that you have continuity cross this soldered blob, by putting a multimeter on the circuit either side of the solder, you will have to clean the printed circuit to make sure you have good contact, if you do not have continuity across this solder then this is proberly the problem, with a soldering iron, make a new bridge of solder to get back the continuity across this point, and this should fix the problem.
