My P38 hates me.

Have a few problems, maybe some could help me out on these.

1. Door only opens from outside now. Decided to do that. However, it never worked properly. The drivers door lock would stick, and lock/unlock only if you moved the button up or down, or opened with key (lock was too weak to open with remote)

2. Cracked windshield. Cheap aftermarket?

3. The HEVAC system threw an open book at me, one time only, hasn't done it since, and hadn't done it before, but still gets me nervous.

4. Headliner suggestions? Don't know how to do it myself, don't want to learn either. Want to have a shop do it, but if I go OEM, will it fall again eventually, or???

Let me remind you, the truck was bought in March. Alternator failed the day after I bought it, the windshield 3 days later. Door, 1 week after.
