i have a 1993 with a 2.5 and the fan for the heater doesnt work it used to work fine then all the sudden one day it wouldnt turn on when i try to turn it on a relay under the hood clicks im just wondering if that click means the relay is engaging or if its bad. i checked all fuses and i dont see any apparent loose grounds or anything its very cold and heat is a must! any help is apreciated thank you.
