After I got over the embarrassment of how stupid and reckless I actually was with this issue I had with 2000 eldorado NO BLOWER HVAC....I pulled myself together and said I owe it to the next idioit out there like me who OVERLOOKS the fact that when checking the MAXI-FUSE (4) 50a location in the engine compartment trying to figure out why the new blower motor you just installed is not responding.....WELL, Just because when you check the MAXI FUSE and you get a light from the circut-tester ON ONE SIDE OF THE FUSE, BUT NOT THE OTHER SIDE IT DOES NOT MEAN THAT THE FUSE IS GOOD. ONLY A NEWBIE, RUSH, RUSH, CHECK THIS, CHECK THAT .......The number 4, 50A MAXIFUSE was BLOWN BUT STILL GAVE ME THE INNITIAL "circuit-tester light" ON ONE SIDE BUT NOT THE OTHER AND I THOUGHT THE LIGHT MEANT IT WAS GOOD........(I just had to post this for good or bad)...................My HVAC blower is working fine now.........
