Anyone know where the relay for the heated rear window is in 1993
'106' please?  There are two in box over N/S wing,  but one is for
lights,  and on the other,  the wires all appear different to those
two thick ones connecting to either side of the rear window,  but I
dont know what this one is for.    There is no voltage at the window
connectors,  and all fuses OK,  therefore I reckon a relay fault.  Any
advice welcome,  thank you.
