how do i remove middle row seats in uplander LT

Unlatch the rear leg, tip the seat forward, lift up to remove seat from floor socket.

it has air bags in seat if I unplug it will it deploy others

No, nothing deploys but you will have "service airbag" indicator on dash.I removed my side airbag seats with some difficulty. Four hands is quite helpful in addition to multiple pry bars and screw drivers. Remove the black springs first, pry up black rotating clamps both inside and out of seat base, and use tire iron or equivalent to pry seat out. I've extracted the middle seat! So much more room and convenience!

Does anybody have a link to where I could buy a matching resister for the middle row seats in a Chevy uplander?

I read the ohms and it is 1. I’m trying to turn the service airbag light off.

Just jack wire the resistor into itself to trick sensor.

I purchased a $5 resistor from specialty electrical shop.
