Low beams stopped working on '05 Tahoe

[satori]

Hey guys, long time no login! Anyway, the other night the low-beams on my '05 Tahoe just stopped working. They work fine on high-beam, but oncoming traffic isn't appreciating that. The low-beam bulbs are only about six months old, and they both stopped working at exactly the same time, so I highly doubt that's the problem. I was hoping someone could point me to a place to start looking. Is there a separate fuse for the low beams from the high beams? Maybe the switch? A relay?

There are 4 fuses one for each low and one for each high. I would try that first. It is also possible that it is your high/low switch on the steering wheel. Mine went out on my 2001 Silverado

Thanks Daniel. All the fuses are good, so it's looking like it's probably the switch. Was it hard to replace? How much did the new switch cost?

Try jiggling the switch to see if the Low beams come on, just to be sure its the multi function switch. Have replaced 2 lately for people. Working the MF switch caused them to light briefly. Would bet this is the problem though

 

Part is around $100 most places

have you checked the relays?

[satori]

No. Do you know where and how?

[desrtrat]

there in the fuse box in the engine compartment. HDLP-LOW is the relay you need. under the cover should be a diagram of where it is, or your owners manual..what i have done is remove the relay, they can be hard to remove, but wiggle it and lift and it will come out. use your fingers, and NOT pliers. i have used the ac relay and replaced the low beam one just to test. if your lows come back on then just pick up another relay. if not, then trouble shoot your switch..

 

good luck

Thanks, but the relay didn't make a difference. So bulbs are good, fuses are good, relay is good. I guess that only leaves the switch. Thanks for all the help guys.

Check the wire connection into the headlamp bulb socket. Socket might be burned up, common issue.
