The functions that have failed in your 2004 Chevrolet Trailblazer are all controlled by the liftgate control module which is located in the liftgate. The module could have lost power, ground, communication signal, or failed internally. There are two fuses for the lifgate module, #2 LGM and #19 LGM/DSM. Both fuses are located in the fuse box under the passenger seat behind the driver. If the fuses are OK chances are the liftgate trim panel will need to be removed to check connections and inputs at the liftgate control module.
