Since summer heat is at its worse I thought of installing a rear blower... Inspired by the rear aircon of the BMW X5, here's my DIY version 
bought this universal type blower assembly
I will install this inside the armrest... So I had to cut away the tub inside.
Then I cut a hole at the back side of the armrest
Test fit...
The install the louver
A peek underneath...
Reinstall the lid and the spacer so I can still put small stuff inside the armrest compartment
Finished product, ready to be installed in the truck!
