took my motor into to get the moog ball joints fitted. Now fitted although they broke one of the ABE sensors

getting it replaced and fitted on Monday got the motor back as I need it for the weekend obviously without any ABS.
Anyway my Outside temperature readout is not working was working when it went into the garage but now it is always reading 0c or 32f why would this be what have they done could the garage have done something to this sensor also.???? or is it just my bad luck.
Help advice needed on how to get it fixed.
