2004 Toyota Tacoma Inside Rear View Mirror

Hi Brian, Is your vehicle double cab, extra cab or regular cab? With or with map lights? Do you mean to say the mirror has detached itself from the base? I have 2 diagrams for the mounting points of different mirrors.

I just had this same problem with my 2003 Tacoma, after I smacked the rear view mirror out with a 20' 2X12. I had a plastic retainer piece and the mirror, and the mirror didn't seem to sit in snugly when I tried to just put the two pieces back in.

My solution was to remove the entire mirror / light assembly by removing the 4 screws mentioned in the diagram above, and also the wiring harness for the lights. I found two small squeeze pins (about 1/2" long and 1/8" diameter) that had jumped loose from their pressed in spots, which sit inside the mirror housing just to each side of whole where the mirror mounts. I pulled these pins out, rotated them so they were oriented correctly, and then re-assmbled the housing. Problem solved!

I had pull my rear view mirror off. It does not simply "pop" back on. You will need to completely take it apart and put it back together. While it's apart the small metal piece attached to the rear view itself must be removed and attached from the top like a sandwich. Basically attaching both pieces before you put the four screws back in. It's all about getting the grab pieces under the small metal piece that is attached to the rear view itself. Sounds complicated but it's not. The diagram is very helpful. You can do it.
