If you were able to locate your problem. I think the electronic unit replaces both relays in the trunk and the sequencer, right? Your other suggestion was the relay under the dash. That makes some sense. Did you try to replace it? Mine flashes only most of the time, but when it doesn't flash the light on the fender only pulses and the third light doesn't work. I think I'll try to replace the relay under the dash on mine as well, based on Joe's suggestion.
