I have had to replace this before but my hubby did it, well he is outta town so Im on my own, I unscrewed it but now I cant seem to disconnect it from where it supposed to, you know like the wires, theres a red tab, tried pulling pushing, up down side to side, its supposed to be so easy that you can do it in like 5 min, well not me, i tried last nite and this morning, need to get it off so i can go return it for another one asap, since its sunday they close early, where on red tab do you push or pull or whatever, help please

A desperate mommy

 

After you slide the red tab, you should be able to unplug the sensor from the harness. The red tab locks it. If you have slid it and can't unplug it, try sliding it the other way, then try unplugging it.
