refrigerator not cooling but freezer works fine

i have a haier hte18waaww refridge. the freezer works and the fridge part does not. i took the panel off of the back wall in the freezer to find there was no fan. (i read somewhere that theres suppossed to be a fan that pushes the air into the fridge) haier’s website does not acknowledge this model and i can only find the most limited of info on this product. i think i need that fan(which i cant find) but im not sure. Can you help?
