Hello… does anyone know how or can anyone provide a link to how one replaces the rear blower motor in a late model Express factory rear air module? My manual doesn’t say much and I am unable to find any definitive instructions on the internet. I searched this forum with no luck. It appears that all of the housing screws for the removal of the cabin-facing half go in from the back side (between it and the body) or the bottom which appears to make it impossible to remove without removing the entire unit which requires a full evacuation and recharge. I haven’t tried yet, but I wonder if loosening the mounting bolts may provide enough wiggle play to pull it out and reach the back screws. Any help is much appreciated. It’s HOT here in AZ and that rear air is mandatory. Thanks!

 

there's nuts on the bottom exterior of the van bolting the whole thing to the floor. Undo those and there should be enough play to get to the back of it.

 

Thank you very much. I was hoping that might be the case but wanted to see if anyone had actually done it before I spent a lot of time in 115 F experimenting. I’ll try to see if I can do it tomorrow and will report back. Thanks again.
