My radio and windows have begun to stop working, its very strange but they seem to work when going slow or stopped, but when I take off radio goes out, windows won't work sometimes its the wipers and even the sunroof, but not always the same combination but when it happens its always the radio and windows that wont work.

Any ideas where I should start looking?

I would check the ground cables as it sounds like a bad ground to me

I think i found the problem. I seem to be charging at 18volts when revving and low enough at idle to let things work so it looks like my regulator is toast.

Ouch
