sometimes,always in the wet,my fuego's dash sounds like it has a canary in it. at first I thought it was the speedo cable,as it only hapens with momentum, but discovered that my drivers side interior light pulses in sympathy with the canary,making me think maybe the canary is the light-on alarm,and the problem is in the electrics,not a physical rattle.Any pointers would be appreciated,as I dont have a clue where to start and it's begining to do my head in.
