hello and thanks for using( just answer). in order to diagnose the system you must have a multimeter. sounds like you have looked and tried several things but you must know where you have voltage and ground and where you dont. first just because a fuse looks good doesnt neccessarily mean it is good. it can be checked with the multimeter.the easiest place to start would be checking voltage and ground at the blower connector, the resistor next. i will try to download the schematic. my home computer has been giving a problem with acrobat reader. i know i can thursday from work. ok. thanks ,Jeffrey
I WOULD LIKE TO SEE THE SCHEMATICS BEFORE I ACCEPT, JUST IN SOME WIERD CASE I DON'T GET THEM
MY HUSBAND SAID HE HAS USED A METER TO DO THE TEST, SORRY I WAS NOT AWARE OF THAT WHEN I WROTE YOU. HE HAS DECIDED TO TAKE IT IN FOR REPAIRS. THANK YOU AND HAVE ADDED YOU TO MY FAVORITES.. FOR THE FUTURE.. MARSHA
