Trouble with ignition (antitheft?)
A few things about myself: I do not know a lot about automobiles, so I apologize if I do not communicate with automotive efficiency. I have never posted to this or any other forum, so I apologize if I do not follow proper etiquette or post something in the wrong place, etc.
On to the problem: I have a stock 2000 Bonneville SLE. It has manifested many of the issues common to its reputation. I recently noted soaking wet floor pans with loss of secondary accessories at all doors except the driver'*. Using the advice found on this forum, I have been able to clear and reconnect the sunroof drains and restore operation to all door accessories by fixing the connection under the driver'* seat. (Many thanks to the participants and moderators which make this sort of education possible.)
While working in the driver floor pan, I came across an electrical junction which connected six white wires and three yellow wires separately (but in the same harness). I fused the 6 white wires together and then fused the 3 yellow wires together (as this appeared to be the function of the junction) and completely removed the heavily corroded and highly oxidized junction.
I reassembled the interior. Now the car will not start, the horn does not work and the headlights do not work. I am assuming that this malfunction is somehow related to the antitheft system. I am also assuming that it must have something to do with the aforementioned wiring harness which I modified. But I am not certain. Prior to performing this work, I did not have any ignition problems at all.
When I insert the key and try to crank the engine, nothing happens. I can hear a relay ticking in the rear under seat fuse box. The driver display module indicates recognition of the key by displaying: "Driver 2" in the display. If I attempt to crank the engine and then leave the key in the 'ON' position, the 'Security' indicator will stay lit solid for 3-5 seconds and then turn off. (The DDM also says: 'Recalibrate Compass' , if it matters somehow?)
I have inspected the fuses; removed the fuse boxes and checked incoming wires and grounds; I have removed the dash covers to make sure I did not disturb any connections while replacing them; I have locked and unlocked the vehicle using the key fob; I have manually unlocked the doors using the key; I have disconnected the battery for 30 minutes and touched the cables together; I have inspected the battery cables and body ground; I have tried the 30 minute Passkey3 relearn procedure at least 5 times; I have removed the driver'* seat and carpet and inspected the new connections. None of these attempted remedies have changed the status of the problem.
The only thing I noticed which changed anything was the removal of the Ignition mini-fuse from the engine fuse box. I simply removed and inspected the fuse and then reinserted it in its place. Prior to doing this, all the dash gauges would reset themselves every time I attempted to crank the engine. Afterward, the dash does not reset, but the ignition, horn and headlights still did not respond. (Also, I believe the dome lights are not working either.) I personally did not assign this development any significant value since it didn't help with the real issue at hand.
Hopefully, this isn't too lengthy. I imagine that providing as much information as possible up front might help to eliminate questions anyone may have.
One final personal item which I hesitate to mention is that I inherited this car from my son who passed away in active duty service with the US Army. I do not mention this for attention or sympathy for myself. To the contrary, I only mention it is a nice reminder to all of the folks that participate on this forum. I could take this car to a garage and let them work it over, but I have found a lot of joy and peace and pride in doing this work with my own hands. It keeps me connected to a memory I do not wish to lose. And as I mentioned earlier, having the knowledge and confidence to take on these projects is a product of the guys and gals that get together here to help out complete strangers. In other words, I'm thankful for what goes on here, because sometimes it'* about more than just fixing the car.
