The heater blower has stopped working on 1, 2, 3, setting and is only working on number 4 (full on). There is a clicking sound from the fuse/relay box when I select number 4. I have checked fuses but am not sure how to test relay's or what or where the relay is for the heater blower if that is at all the problem?

I AM UNABLE TO DO ANY RESEARCH ON YOUR VEHICLE IT DOES NOT SHOW UP IN ANYTHING AVAILABLE TO ME

YOUR PROBLEM SOUNDS VERY MUCH LIKE THE "BLOWER MOTOR RESISTOR" HAS GONE BAD

MOST LIKELY, THE BLOWER MOTOR RESISTOR IS A PLASTIC BOX ON THE OUTSIDE OF THE HEATER BOX. THE HEART OF THE "BMR" STICKS INSIDE THE HEATER BOX AND IS COOLED BY THE AIR MOVEMENT INSIDE OF IT

THIS IS NOT YOUR RESISTOR! THIS ONE IS FOR A 2004 CHEVROLET IMPALA. YOURS PROBABLY LOOKS DIFFERENT, THIS IS JUST AN EXAMPLE OF HOW MANY SORTA LOOK. THIS PIC WAS IN ADVANCE AUTO PARTS' ONLINE SITE
