Thanks for the response Jeff. I will be examining the defrost issue probably next weekend. My windshield frame does not have the vents in it, but I do have some space to work with, I may be able to put some small turn-ups on the oval openings where the wiper linkage is, to get defrost. We'll see. The pictures of your pvc ductwork though are perfect, I will definately be doing something similiar. Either pointing the vent straight up, or out, not sure which yet. I also may get a CJ dash pad and do something with it, for defrost. I spent most of today finishing up the dashwork, and cleaning up the old wiring harness that was there from before the Wagoneer motor was ever swapped into it.
I've finished it for the most part, still having slight issues with the headlight switch, and the fact that only I found only one funcitoning vent control under the dash, not sure what the others control.
^ Cut the lip off of a rubber pipe to pipe adapter from the plumbing section at Lowes. Used it around the speedometer, perfect fit. I sprayed it with rubber undercoat so that it's not quite so obvious that i have a piece of plumbing on my dash :P
I was wondering, IF anyone could identify the vent levers under the dash, and what they do on a 89 or so YJ?
There is a vacuum operated lever up next to the windshield, is this for defrost?
What are the other two exactly?
