Neither of the front sidelights were working. According to the Haynes manual the bulb failure units for the sidelamps are in the boot on the rear bulkhead. This is true of the two units for the tail lamps, but I found that the front LHS failure unit is mounted next to the small fusebox on the passenger side footwell area below the dash. This unit had failed and having bypassed it, I now have the front left sidelamp working. However, I cannot find the bulb failue unit for the front right sidelamp. I think the supply is separate from the LHS lamp because on the RH inner wing where the wiring connectors come through, the red wire to the side lamp is connected via a bullet connector to a red wire that joins the loom headig towards the dash area. The wiring diagram shows four individual bulb failure units for sidelamps (one for each corner of the car)
Does anyone know the location of the bulb failure unit please? I cannot locate it.
The bulb check unit seems to be the device to which the signals from all the various bulb failure units are fed and connects to the warning lamp on the dashboard.
It seems to me now that UK market cars had a single bulb failure unit for the two front sidelamps. Having bypassed that and got the LH sidelamp working, I have since found a separate fault on the RH sidelamp (poor ground) and have now resolved that problem. So I am pleased to report that all my lights are working properly now.
