Tried changing the bulb?? Or checking the fuses?

I'd do it in this order:

1.fuses
2.bulbs
3.flasher relay
4.plugs/connectors
5.check all wiring

Have you changed anything recently like your speedo etc? and is it all the indicators on the passenger side are failing to light, does the telltale on your dash flash when you indicate?

first off is your clock/interior light working? (Fuse 16 - 20A also the fuse to the hazard permanent live)
are your brake lights working (Fuse 7 - 10A also the fuse to the ignition live only indicators)
if the answer is yes to both then your fuses are fine....

try taking a known working bulb from the drivers side and swap it with a passenger side one, test... do they work?

if your drivers indicators are flashing, then the relay is fine and read on...

if your passenger indicators are flashing correctly then you can rule out the relay and any fuses as the passenger indicators use the same fuse and relay as the drivers side.

If the passenger indicators are flashing when you use either the indicator stalk or the the hazard switch then neither of those are at fault as the stalk and hazard switch have separate outputs that later combine and the stalk uses a 12v+ feed supplied by the hazard switch, you could understand one side failing to flash, say when you try the stalk, but you would expect the hazard switch to flash them as and i would bet it would be pretty high odds for both the stalk and the hazard switch to go at the same time as each other.

if you have a multimeter, remove your cowl and probe the back of the indicator stalk socket in the black+white trace wire (the black+green trace is the passenger side and the black+white+green is the feed from the relay) then indicate left to see if you get an intermittent 12v+, if you do then test the hazard switch by keeping the probe in the same place, return the stalk to the off position and press the hazard switch, it should then get the same intermittent 12v+ as before, whilst your also there test the black+green trace to make sure your testing it correctly as you know the drivers side works and thats the wire for them.

if you do get the intermittent 12v+ on the black+white trace wire at the indicator stalk then remove the passenger front indicator and test the same wire there, if you fail to get it there then you may have a break in the wire behind the dash, but thats also about as unlikely as both switches going at the same time.

just give it all a go and post back how you get on
