Ok so I jus got a 85 runeer and 2 days after u notice stuff wrong but I don't know how to go about it. 1st I notice my windshild is dripping and I see rust small very small but orange at that and me ect norm and power buttons work when I push on them but don't stay on. Also don't know how to engage my 4wd. Yes I'm a newb first 4x4 but I'd like to keep it so any help I can get about fixing these things plx help

 

Do you have the sunroof? If so, you'll get a leak at the top of the windshield every now & then. Repair requires removing the windshield. How can you tell that the ect button is not staying in one mode or the other? Don't know how well it works on the 4 cyl., but on the V6 both modes suck. 4WD - the front hubs should have a rotating center piece. Point the arrow to 'Free' and shift the transfer case to 2, and you're in 2wd. Point the arrow to 'Lock' and shift the transfer case to 4H or 4L and you're in either 4 High or 4 Low. In the odd case, you'll have automatic hubs with a solid centerpiece. In that case, just shift the transfer case, but you'll probably have to back-up 10 - 20 feet when shifting from 4WD to 2WD to unlock the hubs. You don't have to, but it really helps the mpg!
