96 Caviliar with no blower fan?

[fritcr]

Has anyone had a problem with the blower fan completly quiting? I took the fan out and it has no juice going to it. I took the resister off and it has no juice going to it either. I also took the dash apart and unplugged the switch and there is no fire their either. The fuse is good and there is fire at the fuse. I switched the relay under the dash with the coolant fan and that did not make a difference. We live in Missouri and it is getting cold here. I don't know what else to try except to take it and I can't afford to do that right now. Any help would be greatly appreciated.
I'm also having trouble with one of my injectors leaking gas. I got a o ring kit but it still leaks. The kit had 2 of the larger o rings in it so I will try to take it out and replace that o ring again to see if it will seal up. Is there a trick to replacing those? Could it be leaking from somehow inside the injector where it plugs in or something? It runs fine.
Anyway, thanks for any help!
