She runs great, 28 mpg, nice ride, lots of pep (for a diesel), perfect body and paint, 170K miles, 3 problems right now. Where do I go, which forum, none says 300 series, there is a diesel section, but the engine is not my problem.

1. A/C unit, center vents don't work and cold air comes out the middle defrost vents when the A/C is on, so the lower windshield fogs up.

2. Sun roof was open and would not close. I didn't have the $$, so I asked a mechanic to just shut it. Any ideas, diagrams on how I can repair myself?

3. It runs hot, always at 80-100, and when the A/c is om or going up a steep bridge, it goes into 110 +. I have flushed the radiator good.

What do I do??
