Accessory headache

[Mike Alexander]

Hey guys. My '93 sierra doesn't seem to have a keyed acc function. Lock, dead spot with no power, on, and start. I tried and cannot turn the key back beyond lock. Anyone have any experience with this? There's a clear "detent" feeling spot between lock and on. I'm assuming a bad switch on the bottom of the column? Any help is much appreciated!!

Do you have a spare key?

What he said ^^ - if the key is badly worn sometimes the tumbler will act up. But, usually, it's the tumbler itself that is the problem.

I had a new key made, which I understand wouldn't fix anything in that case. But the key doesn't appear to worn or brassy......I assume acc should be towards the steering wheel past the lock position?

Did you just have it duplicated off the old key or cut from the code? The duplicate will have the same flaws as the original.

ACC position is on its own, reverse from the other positions, turned back from LOCK towards the driver.

I know this sounds fishy, but trust me. If you know someone with another GMT-400, try his key. My 97 was a replacement for another 97 when it was wrecked in 05 and the original 97’s keys fit my truck. The other day I pulled a key from a Tahoe just for the heck of it and tried it on mine. It unlocked my door but wouldn’t start the truck.

That's how my last square body got stolen, and I hear it's an issue with Crown Vic police cars too.

Just as an FYI the tumbler mechanism and keys for a 93 are nothing like your 97. The entire column design changed in 95.

The other key method could very well work as an indicator, hell, mine was broken into with a rake spike that had had the end sanded round Probably didn't start with it or then the thief never tried, didn't have to, because my spare key was still in the center column, had had the truck for two days when they rode off with it
