Hello to everybody!

I have Cadillac Escalade 2007. Just today noticed that my DRL's not working any more. I have LED bulbs on DRL installed and before I didn't have any problems with lights. Low and high beam lights coming on and off automaticaly, like it must be, but not DRL's. I chacked bulds, fuse and wiring from fuse to lights - all OK.
Do anybody have any idea why my lights are not working? Is any OEM relay installed for DRL and if so where it is located?

I am sure you know this that your truck has to be in drive for the dtr lights to come on, did you retry the stock bulbs?

Yes, I know about transmision must be in drive position. No, I didn't try stock bulbs? How it can effect?

Many have had issues with led's in their drl's

----------

The relay is in the underhood fuse block

I'll try to put factory bulds back and see if anything will change. The relay I didn't find in fuse block. Do you know exact position of this relay or may be some number of it?

I only have platinums here and they are different, but the service manual shows the drl relay next to the hi/low headlight relay on the bottom of the fuse block, you have to remove the top part to get to the relays on the bottom, it's all the service book shows. Might say PCB on it somewhere

I checked today, but didn't find any relay for DRL's, only fuse. Also I putted back OEM bulbs and still nothing happening. Below is pictures of my underhood fuse box. If you guys know position of this relay, please let me know, as I cannot find it.

Do you have power going to the fuse? On the drl make sure you have 12vdc and the other end check continuity to ground.

I checked yestedya wiring from fuse to bulbs, I gave 12V DC from battery directly to the fuse and DRL's came ON, so wiring and ground is fine. Look's like there is no power to the fuse, but I cannot find where it comming from to the fuse.

Look in the manual it will tell you how to turn them back on. I believe the light switch needs to be in the auto position.
Start the vehicle
put into drive
set the parking brake
set light switch to auto
look at DRLs ......they should be on

Today I checked my DRL's with Tech2 scanner and they're not working, looks like DRL relay is not working, but I cannot find position of this relay.

Do anyone knows where DRL Relay is located?

Doesn't the parking brake kill the drls?

It does, but it has a fail safe that will turn on drl once in motion with e brake down

I have this problem also. My DRL's don't work . they didn't work when i bought the car, so i went to the dealer and he said the computer is programmed for drl, but they don't work when he gives the ON command via Tech II.
I also gave +12V to the fuse, and they work...

I spoke with Cadillac tech and they told me:

"The DRL relay is built inside the underhood fuse panel. It is a PCB relay, meaning it is soldered directly to the circuit board inside the fuse panel. It is somewhat common for these relays to fail and unfortunately there is no provision for replacing the relay other than replacing the entire fuse panel. While commanding the DRL relay with the Tech 2 you should be able to hear a click inside the underhood fuse panel. If the relay does not actuate or if it does click but there is no power at the DRL fuse when activated then the relay is faulty and the fuse panel will need to be replaced."

Wow. Good piece of information. But unfortunately, i'm afraid to think how expensive the fuse block would be .... :-)

I looked prices for this fuse block in US and prices between 200-250 USD. I'm leaving in Ukraine and for me it's a problem to get a new fuse block, as sellers don't want to do shipping to Ukraine. (((

I looked too. I might get it but maybe in a couple of months, as i already have some expenses in progress and can't afford any extra for the time being. Keep posted if i buy it first :-)

Turn vehicle on, put in drive, and put a flash light on the sensor on the dash I believe. Should be able to cycle the DRL's by applying light to sensor mimicking day light.

I did that already. Also I checked light sensor with Tech2 - all OK, but DRL still off, so looks like it's PCB relay and all fuse board must be changed.

You could wire the fuse to a 12vdc ignition circuit with a diode. Down side of that would be your drl on all the time your ignition is on.
