Sunroof, fan and wipers going out intermittently

[tmarler]

Ok guys...I am needing a little help. I have a 2002 P5 and all of a sudden my sunroof, heater fan, windshield wipers (not the rear one) all go out and come back on intermittently. I am not sure if the power locks and mirrors are effected, but I do know that the radio and lights are not.

I am asking you guys because I don't really have the money to take it in to the shop and have the service men jerk me around being a girl and all. I like going in knowing a little something

Thanks
