Radiator fan resistor rating? (Page 2/2) theogre JUN 22, 03:05 AM quote Originally posted by 87convert: Just ordered a replacement for this resistor from GMPARTSGIANT.com. GM part number 22049799. Still in stock. $75 shipped. Ouch. Typical dealer ripoff price. Digikey and others sell 0.3 Ω (300 m&ohm 50w moisture resistant power resistor for ~ $15. Example: https://www.digikey.com/pro.../RHRD-.30-ND/1166328 Aluminum or ceramic power resistor including OE need mounted to metal and air moving to cool. Unless you show a car in a strict factory class, no-one will notice or care isn't a factory part. even tho resistor is in car, Moisture resistant help when driving in bad weather.
