Heater not working on number 4 setting

Heater wont blow on number 4 iv read about heater resister could someone describe to me how to get to it so i can replace it? pics would be good if anyone has one out there
 
Mines gone also. U need to remove the glove box. Then look for a black and red wire, trace it along and u should find it about level with the centre console. It will be close to the heater, there will be a 6 wire connection block with 2 screws on the mounting plate. Restistor is connected to the mount.
I can get some pics if u require bud, should be able to c easily when the glove box is out
