Contime 905 unit

[chip]

My interior courtesy light has not worked since owning my car (6 years) and told then by a Nissan dealer it was the Siemens contime 905 unit which sits on fuse box above the fuses. At the time I did not do it as it was very expensive to fix.

Now 6years,on last week I put my car into a different Nissan dealer to have work done so asked if while it was in could they give me a price to do this.

They said the part was no longer made and they would fit a second hand part and gave me the price for the total work. I said go ahead as was sick of loading the back of my car in the dark.

Picked my car up on Tuesday paid the bill when they told me the second hand part was not guaranteed.

Long story short since picking up my car the Hazard lights are now not working.
Does this unit have any bearing on the hazards.
To top it off they snapped off a large chunk of the plastic interior trim and did not say anything.
