So the fun continues with this car. As stated the headlights do not work now. I have tested at the relay and if I jumper power to the output of the headlight relay the lights work. I have three powers and one ground to the relay, two are supposed to be power the ground goes to the lights (the one I jump to get the lights to work) and the last is power but should be open when the switch is off and ground when the switch is on.
Now it gets strange because if I plug the relay in and ground the relay magnet (ie trigger) the lights come on but it also sounds the alarm horn. So looking at the wiring it seems to be a very overly complicated system that runs through too many relay boxes, but after tracking all of the wiring the two supply powers to the relay come from a battery power. The one line is output to the headlight fuses and then onto the headlights themselves as power. The ground for the headlights is supplied by the high/low setting on the multi-function switch. So with all that aside the grounds work properly and they change between high and low when switched, but that is while I jumper power to the relay output.
So it would appear that I have a short to power somewhere in the system of the headlight relay trigger circuit. Now this wire goes from the relay and is feed by the retractor/retainer relay. From there I don't know what feeds it because the wiring diagrams I have don't show connection logic. So in the hope of an easy fix I tried replacing all of the parts of the system I could think of with spares I have lying around. So I replaced the multi-function switch, the retractor/retainer relay, and the theft module, and none of them had any effect. So I am wondering if anyone else has run into this problem and where the alarm fits into this mess as when I jumper the trigger wire the alarm horn sounds.
The alarm seems to function properly, it sets like it should and if I unlock a locked door with the window down the alarm goes off and the lights pop up but don't flash although the horn does work like normal. So anyone got any ideas as to what the problem may be? The wiring runs around a large area of the car and I am not sure if I am looking for a short to power or maybe a loss of ground but when the alarm comes in to play I am not sure how it affects the system. Btw the lights were working fine and then just stopped. I did put led turn signals in it around the same time but they don't seem to have any common ties to the headlights except through the switch that turns them on and they work perfectly.
