thanks for your advice...

The fuse is fine and I have control voltage at the motor connector but no switch voltage is present at the motor connector...

Then you probably have a problem in the harness that goes through under the carpet. It goes to the right of the drivers seat. It could also be the connector between the rear harness and the front harness. That is inline near the steering column.

More information at I had to replace one on a 98 and a 2000 Blazer. First the panel on the tailgate has to come off.Then un-bolt the motor and sneak through the metal tailgate. Little bit of a maze but can be done with patience. Before you install new one plug in power and try. It will save you some grief installing and finding it is junk. Here is the PROBLEM I bought replacements from Autozone and had to try 3 on the blazer before i found one that works and then it was slow. The 2000 the same but after 2 motors I got one that worked. Seems whom ever is re-building these for Autozone is not to GM Specs. They suck. I would recommend one from a wreck or get one from the dealer. You might pay more but it will work. What happens to the motor is where the nylon gears are in the housing they break or get gunked up and bind. Actually the 2000 had water/moisture in the gear part and was all seized. Good Luck
