I just worked on my Honda CRV RD1 cooling system fitted new head gasket, overhauled radiator after not driving it for about a year. I also found that radiator thermostat was removed by someone working on it previously. Cooling fans are NOT WORKING after I just did a test drive even temperature gauge goes 1/3 high. But both fans come ON when I bypass fan switch. I also tested fan switch by boiling in pan and had the test light comes on when water boils. I believe the radiator fan switch is faulty with low voltage flowing through. Anyone to confirm this before I buy a new switch please?
