I have a '07 Honda Civic EX coupe. My high mount brake light only works when its cold outside (i.e. 40s or below) and won't work when its warmer out. The other brake lights work without any problems. I was wondering if someone could explain to me where to look to fix this problem (i.e. is the wiring default in the back panel or with the brake). I am not an expert by any means with wiring or cars. However, the dealer is asking for $389 dollars to replace the LED.
I don't think there is anything wrong with the LED though as it clearly still works.
