Re: Valet key - power key problem
 

OK, I tore the dash apart. The bulb was burned out. I replaced the bulb and it now reads out on the dash. The key switch works, but is a little loose. I turn it from normal to power and there is an area on the power side that has a dead spot in it. As it enters power mode it turns the light on. If I continue to "full" on it goes out. If I force the key to the very end, the light comes on. So, I think I am going to need a new switch.
Now for the power. I will go drive it again, but there still doesnt seem to be much difference between the two positions. I dont know if it is programmed to be on all the time. The car came with a spare chip. The one that was not in the ecm was marked AUAH. The one in the ecm just had a sticker on it that said 90 corvette zr1. Hand written. So, I removed the one that was hand written and replaced it with the AUAH. Did not notice a difference.
Does it sound like I am going the right way?

The light is turned on by the ecm. If it toggles with the switch, it's working properly. If the switch is sloppy, it can be taken apart and easily fixed. No need to buy a new one.

The auah prom is not the latest. I would put back whatever you had previously.

The contacts in the switch get sloppy over time. Best to leave it in full power all the time anyway. :dancing

Since you have already pulled the panel, take the switch apart and tweek the contacts. Pretty easy fix. When you put it back together you will feel the difference in the stops in the switch.

Fixed your image.

Also, if you aren't noticing a difference when the light is out vs lit, maybe your secondaries have other problems. As I've said, the difference is significant above 5k RPM.

I am going to drive it for awhile and see if i can tell.
