I just bought new door actuators for my 89 stang from LMS
My passenger door works but my driver side doesn't want to work

Could be a bad switch and or a wire grounding out

But the old one worked perfectly jus buzzed when it will lock

It has power cause when I pull it out n press the button it works great

If it works when u pull the switch out but not when installed it sounds like the switch is grounding out

I put my old one back on and it works perfectly except the buzzing noise when it locks
So can it still be my switch

Could be that when you put the switch back in its putting pressure on the wire and not letting itself contact when you push it!! Make sure that its not touching when you reinstall it!
