The fan has suddenly stopped working, though the A/C seems to be OK. Is
there a fuse/relay controlling this? I cannot even see how you access the
fan easily to check whether the control resistors have "liberated"
themselves. Short of a sledgehammer, can you get your arm in to see if the
blades still turn?

See the thread "760 Heater fan", everything there applies to your car
too. The fan uses the same fuse as the A/C clutch, so it doesn't sound
like you have a fuse problem.

Which sort of air-con does your car have? Is it Manual or ECC?

All the best, Peter.

Thank you both for your contributions and comments. In the end it proved to
be the motor itself that had burnt out with no warning.
 
How did you determine that the motor had failed? I'm having the same
probem and if that's the problem I'd be happy to accellerate the
conclusion of this repair.

Thanks,

Blurp et al,

If you can isolate the wire that feeds the motor down stream of any
controls, then you should see a resistance value between this wire and
ground of 0.5 Ohms to 0.7 Ohms with a DVM. This applies to a fan motor
of about 115 Watts to 130 Watts (found in 240 and other Volvos). Or,
using a 3 V battery and a small bulb, the bulb should light with almost
normal brightness when connected between the motor feed wire and ground.
If the resistance is infinite, or the bulb does not light, then the
motor has failed. Alternatively, if you have access to some jumper
wires with crocodile clips, you can route 12 V battery power from the
fuse panel to the motor feed wire. If it does not spin, the motor has
failed.
