Battery keeps goin dead b/c fog lights wont turn off

Have the bulbs been tested and they are good? Do you have power to the lights? if not check the relay and its fuse. If the fuse is popped you have a shorted component, repair that and replace the fuse and or relay.

good afternoon Anonymous.

The manual for this model can be found here:
https://www.cadillac.com/content/dam/Cadillac/Global/master/nscwebsite/en/home/Owners/Manuals_and_Videos/01_images/2007_cadillac_srx_owners.pdf on the Cadillac website. There is mention on manual page 181 of turning the fog lamps on and off with the Fog Lamp Band. If you look on page 167, it ties an illustration to Fog Lamps, showing you where the band is on the Turn Signal Lever.

Hoping this answers your question!

If it is a turn knob for lights just pull out on knob

Someone may have ran the wiring from the fog lights on the same circuit that the headlights are on and therefore it is taking some voltage away from the headlights, might need to run the fog lights on a different circuit with a fusable link in it for safety.

You probably also have a sweet smell when the fog comes out. This means the heater core is leaking and needs to be replaced. Hope this helps.

Or you could just pull out the relay under the hood, it's marked fog lights, pull the relay out. If your hi beam indicator is flashing with your fog lights on them selves. Could be the multi function switch. That controls turn signals, headlights, fog, I have seen many of those go bad.

seems your battery has already been discharged by the fog lamp! recharge or buy a new one, but you should fix first the fog lamp before hooking your battery! check for stuck -up relay!

1.At first take out the foglight's fuse before you battery is dead. (Fog lights stays "ON" even you leave the car).

2.You must replace the Multifunction control switch =(

Here is the photo of problem:

Fog lights are connected to pin 13,14.
Fog light switch is "B". Because the current is many Amps, contact surfaces are heating up.
After that the contact opening "C" is melting (made of plastic) so the fog light stays "ON".

Follow the manual for taking out the headlight. Remove the entire headlight and the fog light cocket will be accessible to be replaced.

is it on a DTS or is it the marker side light.
