Hi, I have a 2001 Ford Explorer Sport. My sideview mirror on the driver side door got ran into a concrete pillar and the just reflective mirror part got dislodged from it's casing. The power functions in the casing seemed to still work but I could not get the mirror back into it's sockets correctly and recently the mirror fell off while I was driving and the car in back of me ran over it and it's in a million pieces now. So my question is, how do I remove the mirror casing from the door and reattach a new one? What kind of tools will I need (screwdriver, wrench, powertools, etc..) Also, the mirror is a power mirror with a puddle lamp -- are there any wiring/electrical issues I should be aware of? I'm pretty clueless when it comes to cars but I really really would like to do it myself and if someone could give me a somewhat detailed general idea of how it all works or point me to some sources I could look into I'd be very grateful. Thank you.

I have a 1982 Subaru GL, 1.8L Engine (not that it is important anyways). About two months ago the air conditioner and heater stopped working. I turned the air conditioner on, it ran for a few minutes, then stopped. I switched it on and off and it still wouldn't work. I thought it might be the blower, but the compressor doesn't even kick in when I turn the AC on. Could it be the switch? I checked all the fuses and they are all good. Could it be something that I am missing? I really need the it to move air now that it is cold and windows are fogging up. Any help would be greatly appreciated.
