Rear heater fan stopped working.

[Spanktron9]

Sometime in the past 6 months, the fan for the rear overhead heating system in the 100 stopped working. The dash switch and overhead control panel in the rear still light up, but the there is no air flowing through the vents. Anyone have any experience with this issue? Hoping perhaps just a blown fuse for the blower, but don't know where to start looking. Ran a search and couldn't find a thread on this. Thanks!

Heat doesn't come out of the upper vents, just the lower. Check your owner's manual for a diagram.

Well, something is wrong. The upper vents used to put out air and now they don't, nor does the rear fan blower turn on (you could hear it clearly before.) My understanding was that the 99 did not offer rear A/C only rear heat. So no idea what has happened?

99 rear AC was optional. If you have upper vents and controls above the 2nd row, you have rear AC. Check those controls to see if they're over on heat.

Yup. They are turned to heat and the lights are on. So maybe, if I am understanding correctly, the heat is coming out on the floor, and when I run the A/C in the summer the upper vents run. That would explain it.
