Many things could cause that: blown fuse, bad relay, corroded wiring (if you live near sea water or in the North), bad temp sensor (have to have a scantool to check it), or the following.. First are you sure they should be going? They go based on the temperature sensor reading. Are you overheating? If you are not overheating don't worry about it. If you are overheating check your coolant level first. You could have air in the system that would cause it to over heat. If you have air and you haven't taken the system apart in the last month, find the coolant leak.
possible plugged radiator, sticking thermostat, rad fan not working, temperature sensor not working, low coolant level. that's just a starting point. possible plugged radiator, sticking thermostat, rad fan not working, temperature sensor not working, low coolant level. that's just a starting point.
When the radiator isn't working
in the pipes going to the radiator or you need a new radiator
The relief vent in the radiator cap is not working, replace the radiator cap.
Bad seal Bad spring Bad neck on radiator
No.
check thermostat. check engine fan coolant sensor possible locations radiator or thermostat housing. check electric fan working
my drive and 3rd not working what is causing this promblem is their a a promblem with the transmission
easiest way to tell if water pump is working is to run engine until at running temp. then carefully remove radiator cap. with someone slightly reving engine, look into radiator. if the pump and thermostat are working correctly, you will see the coolant moving(circulating) in the radiator
fuse
Low coolant?Cooling fan not working?Radiator air flow restricted?Radiator clogged?Water pump not working properly?Radiator cap defective?
If you suspect a problem, radiator shops can run a "flow test" after you remove the radiator and take it to them. If you don't want to remove and replace the radiator, they'll also do that part for you.
