Your ohm values look OK , a long as I assume you really mean K ohms on the higher readings. [ 2.15/2.85 ohm....those HAVE to be K ohms]]

If the fans come on with the key ON and relays pulled , you have a short on the R15 resistor feed somewhere.

OI also assume you see the fan come on with the key ON before the car is started.
