Hi I have a 1987 Mustang GT 5.0 Convertible, the back side windows wont go up. They will only go done some too, i push the button to have them move and i can hear the side window motors clicking but it must not be catching the windows and pulling them up. Any suggestions on how to fix this? Also sometimes when my car is on the highway and I've been driving around 70 mph it will start to sputter and backfire and i have to pull over and sit for a few minutes and wait then start back up and drive till it does it again. My speed-o-meter is off, its about 10 mph off but when i get to about 45 on the speedometer i checked and I'm actually going 60 mph. Any idea how to fix this? When i turn my lights on it says my brights are on and when i try to turn my brights on nothing happens, also my fog lights dont work. My oil gage and temp. gauge also dont work (thank god the gas one does!) I bought this car thinking it would be a sweet ride and it is, but its my first car, im 19 years old and a little overwhelmed as i dont know a lot about cars or have a lot of money to get them fixed. If you guys can tell me what is wrong or tell me what to look at then my brother in law can fix it he simply doesnt have the time to find out all of the issues, thanks for all your help guys and I hope that you can help me!
