99 Bonneville - Daytime Running Lights

look for a fuse for the drl . ON my F150 it was in the engine compartment.
When the fuse blew everything else worked but the drl.  Not the same vehicle
but something to look for and or try.

There is no separate fuse for the DRL on a 99 - it's integrated into
the headlight fuse.

If you still need this info ..
I have a 2000 Grand Prix GTP, and the way to disable it that works, is to
unplug the voltage reducing diode, which is a large finned object located on
outer wall of drivrs side of dash. Can be seen through an access pnel when
door is open.
If you unplug the diode, running lights will not work, but everything else
works as normal.
I would imagine a 99 Bonneville would be close to this.

I completely removed the DRL resistor like it says on the website
below, but no joy. I pulled the ambient light sensor, still no joy. I
can't find the relay box to look for the DRL relay so that I can
hotwire it. My last option is to find the Park/Neutral Position Switch
so that I can trick the Light Control Module into seeing the
transmission in park which will allow me to turn off the headlights
using the headlight switch at will.

The Pontiac unlike other cars does not have a separate DRL module.
Instead everything is contaolled by the (master) Light Contol Module
which means that you need to manipulate the inputs to the module to
control the DRL. When the Light Control Module gets a "Park" input
telling it that the transmission is in park, the DRL's go off. My goal
is to trick the Module into thinking that the car is in park all the
time. I'm doing all this because I installed HID headlights and they
are flaky when the DRL is active. It's turning into a real pain in the
ass:

What about trying the Buick solution as listed on that web site?
Maybe you have a 99 1/2 that uses 2000 controls.

Yep that's the ticket - the solution for the 1999 Buick LeSabre. On my
car the A7 input to the Lamp Control Module is light green and there's
no A8 input shown in the 1999 Factory Service Manual schematic
(Bonneville, Eighty Eight, LSS, Regency, and Le Sabre). I can just
wire a fused ignition input voltage from the remote start to that
input which will solve my problem.

There another way to do that since the input to A7 comes from the
Park/Neutral Position (PNP) Switch (mounted at the transmission
linkage). It would be an easy thing to cut the wire right there and
apply the 12 volt ignition wire and not have to take anything apart
under the dash board.

Why would you WANT to disable DRLs????????

Just let the dang things light up. They don't cost you ANY gas.
They are required by law in quite a few countries - and  the beauty of
the Pontiac system is it is impossible to walk away from your car
leaving the lights on if you just leave it on automatic.

The reason why to disconnect the DRL is bacuse they don't play nice
with HID headlights which REQUIRE full voltage (12 volts+) to work
correctly. DRL only supplies around 8-10 volts which causes the HID
headlight to frequently not work or flicker.
