Passenger side rear window will not go up and down., it was hardly used at all and now motor is broken and window will not work. *tr

I purchased my 2005 nissan sentra in december 2005. in september 2007, i began noticing that my car was overheating. in addition to my car overheating, the heat stopped working. i do not have very much money and my warranty has already expired so i had a family mechanic look at the car. i had the water-pump replaced, the radiator flushed, the heating and cooling sensor replaced, belts and hoses replaced. after having so many things done to my car, the problem was still not solved. i then decided to take it to a repair shop. the repair shop flushed out my radiator. when i picked up the car, the heat was working and it was fine. the repair shop is literally across the street from where i live. before i got home, the car overheated and the heat went out. i took the car right back to the repair shop and the mechanic told me that i must have a head gasket problem. ok, so i went back to the family mechanic because the repair shop wanted to charge over $1000 to replace the head gasket (which i didn't have). the family mechanic replaced the head gasket for me though he didn't see holes or cracks in the original head gasket. this still did not solve my problem. i finally decided to take my car to the nissan service dept. they told me that i needed a radiator, i paid $560 just to have them replace the radiator. when i picked up the car, i didn't make it home before the car began to overheat again and the heat went out. i took the car back to nissan service dept. this was five weeks ago. i still do not have my car. they are telling me that i probably need a head gasket. i gave the ok to replace the head gasket which will cost over $1500. i am still awaiting my car but am not sure that this will solve my problem. *tr

Lost horn for third time. a horn is safety equipment. the nissan sentra i own seems to be falling apart at 20,000 miles. i had horn trouble, brakes squeak like mad, windows squeak when up and down - hardly go up and down, another safety issue. *jb

The passenger side sun visor in my 2005 nissan sentra se-r was always hanging down about an inch lower than driver's side. the passenger side sun visor became completely loose and is now dangling to where i have issues seeing towards the right to see if it is safe to make a turn. multiple issues with sun visors and nissan from an internet search. *tr
