2003 Tahoe rear AC no air blowing

[Chrissie]

Hello,
I have a 2003 Tahoe and the rear AC isn't working. The blower is working but there isn't any air moving out of the vents. I changed out the resistor this morning, thinking that was the problem but that didn't fix it either. Does anyone have any other suggestions that might be the issue? Thanks in advance.

No air from any vents top or bottom in the rear?

Just hope you don't have to replace it. It's like a $1600+ job

If you can figure out how to access the rear unit over the passenger tire by removing the plastic interior covers, see if you can disconnect the duct work and look for crud blocking the coil or the duct. could there have been small critters in the vehicle?
