I feel foolish for asking this, but....what's all involved in getting out the headlight lens assembly to replace the high and/or low beam bulbs in a 2015 3500? I looked all over the owner's manual, and nowhere could I find anything that tells me how to replace them??? Thanks in advance.

 

The procedure is listed in my 2015 2500 manual in the "Maintaining Your Vehicle" section. Page 821

Base Quad / Premium Bi-Halogen: Low Beam
Headlamp, High Beam Headlamp, Front Park And
Turn — If Equipped
1. Open the hood.
2. Disconnect and isolate the negative battery cable.
3. Remove the six plastic push-in fasteners that secure
the upper radiator seal to the grille support and both
fender ledges.
4. Remove the two plastic push-in rivets that secure the
upper radiator seal to the radiator.
5. Remove the upper radiator seal from the vehicle.
6. Remove the two headlamp assembly attachment
screws.
7. Reach into the front wheel house ahead of the front
wheel, remove the fastener, and lift the cover over the
access hole in the front of the wheel house splash
shield. Access to the rear of the lamp can be gained
through this access hole.
8. Reach through the access hole of the wheel house
splash shield and lift the slide lock upward far enough
to disengage it from the lock post on the back of the
front lamp unit housing.
9. Remove the headlamp assembly. Grasp the outboard
edge of the lamp and pull it straight forward to
disengage the ball stud from the plastic grommet.
10. Disconnect the wiring harness connectors from the
bulb socket.
11. Replace bulb(s) as necessary.

NOTE: There are access covers over both headlamp bulb
access holes in the quad front lamp unit housing (if
equipped). These covers MUST be reinstalled after the
bulb has been replaced.

 

Thanks...appreciate the info!

 

What a procedure! I looked this up because the day after the *********** did an oil change on my '15 (it was a free-bee) the passenger side low beam was not working. Turned out to be a loose connection, but I was at a loss looking at this.

 

It's not as bad as the instructions make it sound. I've had my lights out numerous times, I've got it down to a couple of minutes to have the grill and lights all popped off

 

The above instructions are AFTER removing the grill?
Low beam light went out again. It has been flickering randomly. Called the dealership and they said it's under warranty and bring it in. Even if it is just a bad bulb, no charge.

 

Found this on YouTube of how to remove headlamp assembly on 2015. Excellent video. I am pretty sure that this is the problem with my truck, but going to make the dealer fix it under warranty.
