This problem happened after I changed one of my headlight bulbs--maybe just a coincidence?

All of the following stopped working at the same time:
1) Intermittent Windshield Wiper
2) Door Chime
3) Rear Defroster
4) Power Antenna

They must be connected the same circuit as they all went dead after changing a light-bulb. I checked all fuses inside the car and under the hood and they are okay. Once in a blue moon they will all of a sudden start working again for a short period of time and then die again.

I thought it might be a bad relay so I checked the Haynes Manual, but it looks like only the Intermittent Windshield Wiper and Rear Defroster have relays, but they are separate anyway.

Any ideas? I am baffled!

 

I cannot remember the name but on the top section of the under dash fuse box there is a little control unit that controls the intermit wipers but I do not know what all else it controls, it is for accessories though. It has a couple of mounting clips that are difficult to get this damn thing out but if your buddy has the same car try doing some swap tronics otherwise you may need to look closer at those fuses.

Rear defroster sucks up some juice so I would think it would be on another circuit.

 

INTEGRATED CONTROL UNIT seems to do something for each of those items you mentioned, just looked up the diagram for you .

 

So the ICU may be bad? Thanks for the info!

Appreciate your help!
