i just recently installed a dvd/cd flip out deck in my truck and after i installed it the radio takes about 15 seconds to turn on after i turn the key on, as well as the windows wont roll down or anything until about 15 seconds later. wondering how i can fix this maybe its just a fuse?! i already replaced the f31 fuse because it popped when i was installing the stereo. just wondering if anyone has heard of this problem before?!?

thanks.
