Sorry if this is a newbie question. I have a 2001 7.3 Excursion that I put a TS 6 position chip in. After the install I checked the windows and headlights and neither worked. I then noticed that the ABS light was on. I removed the chip and called to confirm that it was the correct one. It was, and magically the windows started working! And then they stopped. The radios constant power seemed to be not working...and then it started to work also.
I checked every single fuse and all of them are good.
I read Radio and windows stopped working...
So I don't know if it is a relay or not or should I just start replacing relays. I haven't tried banging on the dash or slamming the door.
Any help would be greatly appreciated.
