Windshield wipers, pwr windows and cd player intermittent

Hello, I own a 1998 suburban 1500, and I have a very strange problem. My windshield wipers, pwr windows and cd player have been working, and then suddenly stop working for no apparent reason. I have looked in my manual and can find no electrical connection to all three. This happened to me the other day while it was raining, and it has also happened without rain. Sometimes it lasts two to three hours, or two or three seconds. I don't want to cause a major accident so please help!:frown:

call your dealer to check about a recall on your vehicle. Several years ago GM issued a recall on 94, 95 full size trucks because the wipers would fail when raining, I'm sure other years were included too just don't remenber as a buddy an I were driving 94 and 95's at the time of the notice. the other items might just tag along on the same circuit????? DK for sure, but its a place to start.
