I finally figured out how to turn off my Auto Headlights for around $30 and still have the ability to use the Auto mode!
This is how I did it.
1. I purchased a new Headlamp switch ( $25-32 Rock Auto). AC Delco #84201596 W/fog lights, #84192536 W/O fog lights.
2. I removed the 4 screws holding the back cover on and using an eye glass screw driver I released the 6 tabs holding the back cover on and removed it (fig.1)

Using the same screwdriver I carefully pried off the Printed Circuit Board (fig.2)

Be extremely careful when taking off PCB. There are 2 copper contacts on the underside,( they are very delicate), that are not attached to anything and might be stuck to the PCB (fig.3) View attachment 18155

I used a toothpick to put one back where it belonged.
3. Using a 1.3mm Ball Burr on my Dremel, ( see fig.3 ), I made a new indentation/seat on switch (fig.4 Before)

Now when I turn the switch to the off position it stays in place, (fig.6) View attachment 18153
NO MORE HIDs igniting every time I unlock my car and I can still use the switch as intended!
4. I opened hood, using the appropriate tools (fig.7)

I created as much slack in cable as I could and disconnected cable at the hood release inside car. I didn't try but you might not have to disconnect cable. If you pull the cable down 90 degrees it should pop put.
5. I removed the 3 bottom 7mm screws of the Panel Knee Bolster and using a flat bladed plastic trim tool I released 3 of the Pain In Ass clips on left side ( fig.8)

I have small hands so 3 gave me enough room to reach in and depress the 4 locking tabs and remove the switch. I removed electrical connector by depressing locking tab ( fig.9 )

and installed new switch.
6. I put Bolster back together and reconnected hood cable. Reconnecting cable is a bit tricky but if I can do it you can do it.

$135 on RockAuto for GM bulbs
and $55 to $101 for Wagner/Phillips.

GM GENUINE 13594523 Info

LT Model; LED Daytime Running Lamps (T3S), High Intensity Discharge Headlamps (T4F)

Awesome, thanks.
I understand that my bulbs are 25Watts and not the standard 35W.
Is this because the bulbs are more efficient and put out the same brightness at a lower power consumption??.
