In addition to stopped up drains, the problem can be heat leaking into the cabin through the front heater valve if the valve is bad and the foam seals are not good.

Would someone please point me to a good work up or two on doing this job?  A video might be nice also.  I have heard that it is a lot of fun and a quick job(yeah, right, like that happens).  All kidding aside, I would like to know of any spots where the Bentley may be vague, or of interesting (read easy) ways to support the cabinet, which I believe needs to drop somewhat to do this job.
