Fans not working

No am checking continuity as I understand it, touching the negative probe from one aide and the other probe to the negative from the other end, and sane with positive. With negative is where am getting 500 some or 600 some value, not a negative value.

I pointed the meter to continuity.

There is ground coming from the big wire coming down which connects to the big fan and there is positive as well, but when connected, there is no ground at the smaller fan connector, which feeds from the big fan.

Where is the module?

These videos may explain it better. I also went to Advance and borrowed the whole fan assembly, they let me do that, hooked it up, same thing neither one are running with A/C on.

Any thoughts on these? I can read any numbers from the scanner if needed. Is it possible a high pressure switch prevent fans from coming on?

Now I shook the fan to clean some of the debris and they both worked, still outside the car. And now I turned the car off and both were still running. And even when A/C isn't running both running, check engine and EPC flashing, volts were low left a light on, so I jumped it and that is what happened. Now it wont even start and I cant get the scanner to read anything, keeps saying linking error.
