on a 1991 f 150 does anyone know where this so called Do Not Drop Box is located. it is suppose to control the wipers. it may be called something else. P.S. the wiper motor and the switch was changed . but the wipers only work on high . an not too good on that setting either. anybody have any ideas as to why.
I think the box you're talking about is in behind the glove box...at=20 least that's where it is on my '92 Bronco. Remove the glove box and you=20 may be able to hear the relay in that area when you operate the wipers.

On the 89 it is around the steering column.
can not see anything there after removing the glove box. is it a certain color.
