Heating

The air blend door for the passenger side is most probably stuck due to a faulty air blend motor or stuck/dismounted linkages. You would need to check which is the cause.

THANKS GUYS,COULD YOU TELL ME WHERE THE BLEND MOTOR IS LOCATED.

If you look under-dash on passenger side, it should be at side of heater housing, ie near center under-dash.

It should look something like the one in picture.

THANKS FOR RESPONSE,THE ONLY THING THAT LOOKS LIKE THE PICTURE YOU SENT IS BEHIND THE GLOVE BOX UNDER THE DASE FUREST RIGHT SIDE PASSENGER,IS THAT IT?

Yes, that should be it.
