Daytime running lights won't come on

[pdxrealtor]

I read they are supposed to come on in the day. Mine do not. I messed with all the switches and nothing.

When I use the keychain remote to unlock the car, or lock the car.... Can't remember..., the DRL comes on as do the reverse lights... So it's not the bulbs.

I'm new to hummer.... Am I doing something wrong or ???

Check list to take a look at. Nothing covering the light sensor ? Truck not in park ? Below is from owners manual.



Daytime Running Lamps



Daytime Running Lamps (DRL) can make it easier

for others to see the front of your vehicle during
the day. DRL can be helpful in many different
driving conditions, but they can be especially helpful
in the short periods after dawn and before sunset.
Fully functional daytime running lamps are required
on all vehicles first sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on,

the exterior lamps control is in AUTO,
the transmission is not in PARK (P), and
the light sensor determines it is daytime.

Hey thanks EE!

I haven't checked while not in park....

That will be the next check.

The sensor is on the dash, correct? Just off center towards the passenger seat?

Yup, that is the one for the DRL's. Just be sure nothing is covering it up or it will think it is night time and the DRL's won't come on.

Good luck, Ed

I am guessing it just had to be in drive.
