Hi,

I have a 92' SC400 and my door lock switches will not work on either side. I started to troubleshoot the problem and I only have ~8.5vdc to the switch at the door. On checking the fuses, I found that all that apply were fine. My next move was to go to the door lock control ecu and ended up getting tied up with my schedule. The slots for the key to go into the door lock cylinders are cocked 2 o'clock on both the driver and passenger sides. I can't insert the key all the way in the door. The passenger side will lock and unlock with the key, but again I can only get about 3/8" of the key in the cylinder. The driver’s side will go in the same amount but will not unlock or lock. I probably will be shaving my door handles before I paint the car, so I'm not concerned so much about fixing/replacing the handles or lock cylinders. But I want to mention them as an aid to describe the situation I have. Other things going on are the memory seat settings don't work, and the headlight sensor is either broke or the circuit is bad because the lights do not automatically come on. I don't think that those two things are tied into the door lock circuit, just a heads up in case they are. If anyone can help me with this, I'd appreciate it. I have the manual on my drive already and was using it to help me troubleshoot. I just haven't had the time to finish digging in to the problem at all. Thanks for your time!

 

I was changing the rod clip on my drivers door (door wouldn't open from outside) once fixed remote key fob woudn't open doors. Not certain if this helps but, Turns out the toggle switch under the left side of dash was in the off position. Turned it on now everything works. After owning the car for 6 years I didn't even realize what that switch was for.

 

What toggle switch is this that you speak of?
