I'm trying to help a lady going thru some tough times. I pulled the relay and jumpered the connections and the fans ran. I tested the relay and it works, so something is not sending power to the relay to activate it to send power to the condenser fans. The compressor is coming on, but I've determined the system is leaking refrigerant. I think it's coming from the expansion valve at the firewall.

Thank you brother. That was helpful
Hi there, nice ML. It is possible your power steering fluid leaked on top of the AC compressor.
Do you know where the relay can be sourced? Was it just a bad relay in your case?
I have the same problem, the fan does not turn on. I don't even know how to check? I'm from Ukraine
Try TH-cam videos, I wish I could help you.
