I have a '94 XR2 with power door lock buttons located in the front corner on each door, just below the triangular window. They look exactly like the ones that your '94 Mercury Sable would have. Anybody else have them?
I don't think they would be original, as I can't imagine why anyone would want them. My guess is that they were installed with an alarm/power doorlock system that I have since removed. The only power locking system I knew existed was on some Capris that locked both doors when you pushed one of the usual door-top mounted buttons and the other one locked in unison.
Anybody have info on this? Thanks.
