The "triangle" is part of the door panel. You would not have to entirely remove the panel to access the mirror harness and screws, but you would have to loosen most of it. Door trim removal: http://www.wkjeeps.com/interior_trim.htm#DOORFR
Depending on exactly what is broken inside you may be able to buy a used replacement mirror and replace the part(s) without removing your mirror. Pictures of the assembly can be found at this link: http://www.wkjeeps.com/wk_side_mirrors.htm
Only the glass is sold separately from the dealer, otherwise you have to buy the entire assembly. Searching for a used one is best, but you want to make sure you get the right part number for your Jeep, there are lots of different mirror part numbers. If you want to pm me last 9 of VIN I can get you the exact part number for your Limited.
