Power window & back passenger power door lock will not work anymore. Inside cabin smell of gas fumes at times.

Window behind driver has stopped operating.

Power door lock, behind front passenger, has frozen into the locked position and door cannot be unlocked and opened anymore.

At different times, a strong odor of gasoline wafts through the vehicle. I thought it may be the exhaust pipe; I got that replaced...but the problem of gasoline odor, still exists.

Please help.

Thank you and Happy Holidays,

Charlie
