Question #1- My ac in my 85 300 sd does not work as well as it should. I would like to check the insulation on the line behind the glove box. How do you remove the glove box without destroying the little plastic gizmoes that hold it in place?
Question #2- Where can I find a diagram laying out the routing of all the different vacum hoses, fittings and little valves and such? Everything seems to work just fine, but a lot of the vacum lines are old and brittle, and I would love to replace them, but would dearly love to know what each one does before I do. Anything like a wiring diagram available anywhere?
