I have no headlights... please help

I recently bought a used 2006 altima and the low beam headlights will not turn on. ALL the other parking lights and tail lights work as well as the high beams. I replaced the low beam bulbs, I checked the 2 fuses under the hood, I bought a new headlight switch on the steering column and replaced that. Still no low beams!! What am I missing? Someone please help.

Steve Boylan first here is how they operate.

Low Beam Operation

With the lighting switch in 2ND position, the BCM receives input requesting the headlamps to illuminate. This

input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the IPDM E/R controls

the headlamp low relay coil. When energized, this relay directs power

  • through 15A fuse (No. 36, located in the IPDM E/R)
  • through IPDM E/R terminal 20
  • to headlamp RH terminal 1, and
  • through 15A fuse (No. 45, located in the IPDM E/R)
  • through IPDM E/R terminal 30
  • to headlamp LH terminal 1.
  • Ground is supplied
  • to headlamp RH terminal 2
  • to headlamp LH terminal 2
  • through grounds E15 and E24.

With power and ground supplied, low beam headlamps illuminate.

“I checked the 2 fuses under the hood, I bought a new headlight switch on the steering column and replaced that “, but you did not say you checked the relay. That is where I would start.
