My car has recently lost power for its power locks (inside) however wireless still works perfectly

Also both of my windows have stopped working ( driver was broken before)

After buying the car I messed around with the grounds a little (AC/Crankcase/Main Battery) but had only cleaned them and made sure they where tight...

Maybe I effected the ground for these accessories...?? Where are the grounds for the windows and power locks???

all of my fuses are good, and my switches are good as well... I tested them with a volt meter but they do not move my new motor...

I have located the grounds under the door trim (two gold connectors) but I am not sure they are the ones for the power motor/locks (I am told they share a ground)

any advice and suggestions GREATLY appreciated!!!
