I have the nasty smell coming from the heater. I am pretty sure I need to take the deal apart to clean it, but how do I go about doing so? I started to take apart the dash but I appeared I would need to really get into it and did not have the time. I have a "blow and go" attatched to my ignition so if there is a way to get at it without serious dash work that would be sweet. Thanks for the help.
