So i got in my car last night and my heater wouldn't turn on. like no blower. the switch that adjust speed is turning on and off the ac for defrost i think it works. the switch for mode adjustment works cause on the interstate it'll blow out ambient heat to the corresponding places. the fuses are good, and i have no idea what belt to look at or where the heater blower is located. any help on how to assess this would be nice seeing as how its still very winter... thanks guys. only thing i have done lately is replace a cabin filter... : (

 

anyone tell me possibly where to find the heater blower motor relay in the car? its a 2002 civic Si. and maybe the location of the heater blower its self?
