Turn head lights on every light works except low beams

2009 not the hybrid car , right?
engine runs cars drives,okay, and dash charge/bat lamp not glowing?
check all fuses there are over 7 fuses just for windows
check them all,
not just under hood.
toyota has 4 doors and 4 windows? all 4 dead?
that HL statement is not clear.
low beams dead, in DRL auto or manual mode.
high beams ok.
all windows dead, not just one.? all windows controls on car are all dead, not just 1

HL.
there is fuse for LOW beams, x2, left and right
fuse marked H-LP LL and RL. 10amps each
if both fails,DRL is failing, and if its failing the DLC OBD2 port must be scanned to see why.
1 fuse box underhood
and 1 fuse box in dash left side USA (drivers side)
open glove box take out users guide, see index, see fuses.

check all fuses not just some.


the problems here are
not telling all things working and not. (in brief)
not checking cab fuses
no scanning the OBD2 port

Matt, sounds like you were thorough. I would check the switch. Use a tester or even bypass the switch. If you have power, fuses are good, and its NOT the bulb (because there are two filaments) I would look at the switch then the wires.

Ck the relay switch the high one to the low they are the same also I believe they are fused in the one fuse box under the hood behind the battery

MAY BE YOUR DIMMER SWITCH ALSO CHECK RELAYS IN FUSE BOX UNDER THE HOOD

Don't forget to check the Relays.... Black boxes associated with the fuses... Also there are usually two fuse blocks ONE inside of the car on the drivers side: Under the dash, or on the side of it. TWO is under the hood in the engine compartment area either on the firewall or on one of the fenders usually close to, same side as the battery.

The problem is a Headlight module. Fuse box under the hood has two black modules side by side, the one on your right is the headlight module the one on the left is the fan module. Try swapping them, if the headlights work replace bad module, don't drive vehicle with the bad module in the fan slot. Mine kept going bad because I had a high intensity bulb on one side.

According to the wiring diagram, the left and right low beams are connected to the same wire which is
vt/or. Check for power on this wire. Also check for a good ground on the black wire.

You have a bad switch

You know the fuse for the high beams is good ( Cab fuse panel fuse # 16 ) and the pass low beam fuse ( cab fuse panel # 26 ).
Might want to check cab fuse panel fuse #28 ( this is the driver's side low beam ).

If this fuse has power on both sides ( with the low beams on ) next you can pull the headlamps, and check for power at the connectors, but depending when the last bulb change took place, I would say you need need bulbs. ( need at least 1 for the high beam out )
Confirming with a meter at the headlamp would be a good idea, before spending the money.

The bulb connector has 3 pins.
Black wire is ground on both sides
Light Green w/ Black stripe wire is high beams on both sides
Driver Lo = Dark Blue w/ white stripe
Pass Lo = Dark Green w/ Orange stripe.

hello i no you said you checked your fuse box go under your hood drivers side near your strut tower their problay is a second fuse box its black some times fuses is on the cover you have to unlock the side of cover lift off on inside of cover will list what is what sometimes left and right headlamps are seperate fuses goodluck
