Blower Motor not working

[chappys4life]

Working on fixing the ac in my 1979 suburban. I just recently picked it up like a week ago. When I got it the ac blew faint but was cold. Now all of a sudden no air output is coming out on ac, vent, or heat.

I figured I do not know the last time any of these parts where touched so did some replacing. So far I have done
- blower motor (gm 15-80213) for a 88 chevy to make it blow better
- blower motor realy ultima ut-rlyu0176
- blower motor switch ac delco 15-71517
- added new 16 gauge ground wire from blower motor to rad support.
- cleaned factory ground wire to firewall

Testing I have done
- checked all of the fuses and no blown fuses.
- purple wire from the relay to the fan motor I get no voltage no mater the switch setting.
- If I jump 12v to the new blower it spins fine.
- Old blower motor does not spin with 12v applied.
- Continuity with meter from ground on blower motor & filter to battery
- checked the plug connected to the resistor. None of the wires have any voltage when the switch is on any setting

Any suggestions on what else to check? Its driving me nuts

Fuse panel incase im missing any fuses
