I finally get all the little things working on this 91 loyale, and then the 4WD stops working! It's got the pushbutton 5spd manual transmission, so I've managed to check everything up to the two vacuum solenoids near the right front strut tower, the vacuum seems fine out of there (the front solenoid gives vacuum when the switch is on, the rear one when it is off, you can hear a hiss when the button is pressed). There doesn't appear to be any leaks in the hoses up to the transmission, but that's as far as I've got so far in terms of diagnosing. The 4wd did work when I used it a few weeks back, and it sure would be nice to have it work for the winter coming up, anybody have any hints or ideas as to what I should be looking for?
