i am having electrical issues and i have an 00 yukon denali the radio,wipers, and the windows all go out at the same time and i am thinking it is centering around the factory radio because when it goes out the other two things i described goes out too. as long as the radio is out until it decides it wants to come back on none of the items work. also when the radio does come back on and i try to use the windows or the wipers all three stop working again. i am not sure but i believe these three items are on the same fuse panel. any help would be appreciated.
