Citroen C4 Middle Brake Light Problem

[fuzzymuzzy]

Hi guys

Was wondering if anyone has any ideas on this problem!

I have a Citroen C4, 3 door version. Last week, I noticed that the middle brake light wasn't coming on when I broke, however it is coming on when I put the rear window demister on.

I spoke to my local Citroen dealer who said they had never heard of the problem.

Any ideas?

have you checked the connection at the bul to see if it's loose or grounded
