I just got this 87 4WD LE yesterday, and after much research, found where the side mirror control switch is supposed to be on a 2WD (I don't have the 87 4WD owners manual, so finally found a pdf for the 86 2wd...)
It's right where the 4WD switch is...
I tried adjusting the mirrors manually, and no go, so I believe it is supposed to have a control switch somewhere.
The center console has an empty square hole about the right size, but no obvious wires.
What am I missing?
I'll have other questions on some more serious 4X4 details after I complete my research, but right now this is something I want to get adjusted for safer driving...
