Headlamp adjuster motor

[et_toyota]

Hi

Here is picture of back of brand new headlamp (1 of 2)  fitted by Halfords into Rav 4 1999.

On getting it home realize the beam adjuster scrolling switch does not engage in either of the new headlamps, you can hear the motor, but it does nothing.  Someone told me there is no way of manually adjusting this, so if the motorized adjuster doesnt work then you are buggered????  Surely not? I am taking back to Halfords to see what they say, but would be interested to hear from anyone out there who may know differently, or have any answers for me.
