Maintenance/Repairs

I have a 2019 Ford Escape. I bought it as a rebuilt. Normally the radiator fan runs about 10 seconds when the car turns on. Then it appears to never come back on again. I have replace relays, ambient temperature sensor, and radiator fan. Even when turning on the A/C the fan will not turn back on again. If I jump the relay for the both low speed fan and the high they run just fine. Then when I put the relays back in and turn off the car and back on again the fan comes on when turning on the A/C. Even when doing this several times. Then sometime later the fan just starts only working again for the initial 10 secs. I have tried wiggling wires along the path when the fan is running and they keep working. There has been several times the car was almost overheating and I had to stop and turn off the engine and wait awhile before I could drive it again. I took it to a mechanic who hooked it up to a computer and sent a signal to turn on the fans and they didn’t respond. What can the problem be?
