Still the same issue: broken fan motor, ballast resistor, or relay or its a break in the wiring.
If you switch the relays the passenger fan still doesn't run, then think fan motor or resistor.
If the weather is hot and you let the car run at idle until the fan switches to high speed as the water temperature rises and the passenger fan still doesn't work, then the fan is the problem.
If the passenger' side fan comes on at high speed, then it's the ballast resistor
If you have a Durametric cable or know someone who has one, you can test the fans in low and high speed modes without having run the car.
