I've included a couple of before and after stiches picutures, so if you don't like the sight of blood, be warned. The drivers door power window on our 98 Expedtion was broken, and the best price I could get from a repair shop was around $300, so I figured I'd do it myself. The motor cost me $50 at the local checker auto parts and it looked like a pretty straight forward R&R. I got the window regulator and motor out without a problem, but when I went to remove the motor from the regulator, I forgot about the coil spring (kinda of like a big watch spring) that helps the motor raise and lower the window. I did read the directions that came with the replacement motor and I don't remember seeing any warnings about this or about securing the spring tension. The only thing holding the tension on the spring was the old motor and when I pulled that off, the regulator spun around and part of the metal bracket smashed me in the face, hitting me in the mouth. The braket broke two of my center, lower teeth in pieces, one is broken of near the base, the other is broken at an angle. My lip has about a half inch gash which took three stiches to close. There is also abraisions on the the top and inside of the lip as well. The lip was stiched up at the emergency room last night and has swollen up quite a bit since then. It's sore and as long as I don't try to talk, it doesn't hurt too much. I was able to get a dental appointment today and I'll know more about what needs to be done later today. Bottom line, in trying to save $250, I'm probably going to be spending two grand on dental reconstruction. Life can be a big s**t sandwhich sometime....and right now I can't even take a big bite without hurting!
