1999 TOYOTA CAMRY User Comment / Complaint

I bought a used 199 camry two weeks ago. the first week i noticed a problem with the passenger window. it would not roll up or down after having rolled in down and up severeal times. i mentioned to my brother that i had a probelm with my camry and before i could even state the problem he asked if it was a 1999 camry and if i had a problem with the window rolling up and down. apparently his mother had the exact same problem -- but just turned it in at the end of her lease. the dealer says that it is probably the regulator. this seems to be a common problem although there is not recall on this. dealer says it will cost $400. i am concerned about this problem in the winter ( i live in wisconsin). there is also a considerable safety and security concern. i am not sure whether i will return the car or get it repaired.
