So I've had HID headlights and fog lights in my 2005 ram 3500 ctd. I am not sure if it matters or not if its diesel since this really don't pertain to the engine itself. IF I turned the fog lights on the radio lost reception, But the issue was IF I left my headlights on and shut the truck off the window wiper would wipe ONE time. If I shut the headlights off the wiper would wipe ONE time. If I was driving with the wipers on delay headlights on the wipers would wipe but not delay the wipers would wipe twice, or three times then delay and so on.
turned the headlights off and everything is okay. ODD My thought behind it the HID headlights must have been causing issues with the wipers. So I took them out tossed them in the garbage and installed the factory lights. Everything works fine. but I worry that I may have issues with the BCM or fuse box at a later date. I guess I'll cross that bridge when I get to it??
