I know there's a million threads probably about this one problem but i cant hardly find my exact problem if that makes any sense. i go to turn on my blower motor and it just wont work so i replaced the ignition switch and the blower resistor then i bust out my meter and make sure my fuse is good it is then i go to the plug and its reading 13v on vent and speed setting high at the plug so i plug the blower motor in (brand new) it dont work but when i touch two wires together one on each side of the blower motor plug the motor works what could be my problem bad plug? bad blower resistor? if any help please comment

Do you have ground at that plug?

im pretty sure i do. when i stick my meter in the end of the plug thats permanent to the jeep putting the red lead into the side with the green wire and the black lead into the side with the black wire it shows a clean 13v or are you talking about say like the dipstick grounds on the renix era jeeps one of those kind of grounds

Just making sure the ground is good and you hadn't just checked for power using another ground besides the one you did.
