93 blazer keyless remote programming

could anyone please help . I am trying to program a spare Remote Keyless Entry for my 93 Blazer

:flash: Hello
You should find under the driving wheel a small black connector .
Take a wire and ground the bottom left hand pin (purple wire) with upper right hand pin (think it's a black wire) , the doors + rear windows will open/lock , then press any button on your remote , the doors will
open/lock again . Remove the ground on the connector . Check
the system using remote ...
Please let me know if it works ...

I also need help with 93 Blazer programing. I tried the procedure, but locks did not activate when jumping lower left terminal to upper right terminal. Does ignition have to be turned on?(don't want to burn something up!) Thanks

You don't need to turn on the ignition , in fact you just have to ground the pin G on the black connector (purple wire at bottom left side ) you can just connect a wire from this pin to any ground on the car if you think the upper right pin (ground pinon the connector is bad) is no more
grounded ... maybe that's your problem ..If the programming instruction
doesn't work check if your Blazer have the optionnal keyless entry
or remove the central console (between front seats) the keyless
module is located under this console , my Blazer had a bad module
so nothing happened when I jumped the wires ... then the module
was grounded . Maybe that's what happening to your own Blazer .
The option code for keyless entry is AX3 on the optional chart in the
glove box .

Thanks for the info. Evidently I have bad modules in both vehicles.
The remote used to work on the 93 until recently and I just got the 94.
Thanks again, Dennis
