Muffled "Clicking" every 3 seconds?
I've recently been hearing what can loosely be described as a muffled clicking/clunking that occurs every 3 seconds or so. It's metronomic. It's coming from in the dash area I think. I haven't had time to chek the engine bay, but I don't think I'll be able to hear anything from there.
Does not seem to increase with engine speed. Any ideas?
