Car Help

Okay I have two things that I need help with.

Firstly I own a Vauxhall Corsa and I broke the little reflector on the rear of the car, apparently I have to go to a main dealer to get a replacement but I know they'll charge an arm and a leg for the replacement of a bit of plastic, so if anyone knew of anywhere else I can get one it would be a great help!

Secondly, on the part above my radio where it tells you the time and all of that, the outside temperature gage isn't working and now tells me that it's around 69 degrees outside, anyone know how I can fix/reset this? and yes I have checked that it is not telling me it in fahrenheit.

I really want to try and get them fixed because it's getting annoying now haha, so any help would be sooo good :D

Find a local car techy that will do it cheap? If not take it down to your garage and see what they'll do :)

Is it a Corsa C (2001 - 2006)? if so, you could probs get a replacement one of those from a scrappy or even ebay for about 99p (don't quote me on that) - after all, its only a reflector so there won't be any wiring, just a pop-on pop-off job.

As for the temperature guage, I have the exact same problem on my Clio and it's a case of having the outside temperature guage replaced - i'm not gonna bother cos it'll be complicated/expensive to repair, i don't really care anyway lelelelel
