Power Locks

[tpnotch420]

I have recently purchased a 92 SC400 with power doors but for some reason when I hit the lock button on the door I can only unlock the doors nothing happens when I try to lock them also my keyless remote does not work. I've checked to make sure the switch is on and the fuses are good but I just can't figure this out does anyone have any thoughts on this?

is it making any noise? it may be reading like a door or trunk is ajar and not allowing to lock

May not be connected in the door?

Off topic? I'm not sure how the SC's hook up in the doors but on my Talon I could have half a unit plugged in to the Elec. socket in the door and only one side would work. And by the way I went down to the dealership to see if I could get a remote entry key because I was never given one when I bought the car, it has to be programmed along with $300!, so don't lose the remote. :)

Since your SC is so old, I would bet the problem is in the drivers door contacts. While I have an old 94 LS, I think the problem is similar. Every 6 months or so, I have to take the drivers door control console out, and spray the copper contacts with electrical cleaner spray. I do it when the the windows start to be hard to open, and the electric door lock gets harder and harder to work. Basically, the copper contacts build up a black corrosion. I live now in Vegas, where there is very little humidity or other corrosive atmosphere, yet the contacts still wear down. Removing the console is easy-good luck.

I opend up the driver side door to clean the contacts and make sure all wires were connected In doing so I think my problem has something to do with the alarm if I disconnect the 3 wire plug that goes from the outside door handle to the alarm then the door locks work but I set off the alarm if I open the car even if I put the key in the door any alarm experts out there?
