Hi all, its been a while. Am having an issue that i cannot figure out. I have done searches for past threads but cannot find anything that exactly describes this problem. I have been noticing that there is a thumping noise coming from the passenger side's dash, probably behind the airbag. My blowers and fans are working fine, so i have no idea what it could be. It is inconsistent, the loudness does vary. Any ideas???
