Default Blower Motor

Any advice is appreciated. I recently replaced the AC Compressor main line on my 1980. The hood had to be removed to connect at the condensor side. I charged the system an everything was working perfectly. Later when I had help I re-attached the hood and thus the problem started. The blower will now NOT work. I have checked the wiring along the firewalls thinking I might have disturbed something, pulled and checked every fuse, replaced the blower relay and blower resistor. When I move the blower control to high I hear a click sound, (from the relay?) not sure. On AC setting the compressor does click, disconnected it to see if related, blower still doesn't work. Get the clicking sound on heat/ defrost settings also. Stumped as to what to try next. Thanks

Have you tested for power at the motor itself? Also check and make sure you didn't accidently knock the power wire or the ground loose from the blower motor.
