I have a Nissan Sentra SE 01 and the the cigarrette lighter doesn't work, the passenger power window works on and off and I have to keep changing the headlights. Also the Cat. Converter has to be changed. I bought a new fuse for the cigarrette lighter (charger) but it still doesn't work. Any suggestions as to what the problem might be? Other problems: I was told that the upper motor mount is completely flat, the front brakes are 95% gone, coolant flush (debris bating in coolant) and I have an oil leak in the distributor. I was told that even if I got the cat. Converter fixed, the oil leak in the distributer would cause a problem anyway. Are any of these problems related and because funds are limited, which order do you suggest that I fix the problems? Could any of these problems be an electrical problem? How could I check to see if this is the case?
