Bad earth on the rear, find the earths remove and clean the area they are fixed to and the cables, if necessary add another good earth!!

Danielle, On the driver side you may have stuff in the way, which may have to be removed, to change bulb. Sometimes it is easier to remove headlight then change bulb and reassemble. Videos attached make it look fairly easy to change he bulb with out removal of headlight.
Check the attached links,instruction and guides, Good luck.

Q1: all 4 dead?
Q2: do blinkers work ? hummmm
alldata.com covers all this, log in and read>?
does car run perfectly
do all other lamps work? full bright head lights.
cranks fast not slow
battery charged? main car battery?
then
fuse meter good
fuse haz/turn good?
the tail fuse and tail relay most work or the HAZ switch is dead.
is the haz lamp dead? triangle ICON lamp?> in dash.

the schematic is below.
when you turn on the haz button , this sends 0v (ground) logic signal to the BCM puter.
and the turn /haz relay.
the blinker switch has its own inputs to the RELAY .
so one can fail and other work, and not stated, sadly.
its not really a relay its and electronics module.
(means testing it, is not relay like at all)
12v on both pins on left ? top.
in haz mode 0v on the yellow wire.?
if yes , yes, yes, then the relay is bad



the 48 slot is haz/blink relay module.

You can get to it from under the wheel arch, just loosen the plastic wheel arch liner and it will provide direct access to the rear of the lamp where the parking light bulb is located. That's on a long wheelbase grand vitara. I'm not sure if the short wheelbase one or the xl7 are the same as the light configuration is different.

that is all covered in the glove box operators guide.\
lost?
here it is.

start by checking fuses first,if fuses are good then check the bulbs, start there, good luck,

Just unscrew the screw, then pull hard on the light...it will pop off.

You don't change the light bulb, you have to change out the switch. It is built in the switch, Don suzuki tech
