That sounds like the cooling fan relay. Find fuse/relay cover and check condition of fan relay. It should be labeled. Easy to replace.

Good luck,

How to find out what keeps blowing my fuse and overheating my Nissan Sentra 1.8 2006?


check what fuse is blowing
I suspect that it is a fuse for the fan relay that switches on the radiator fan
if that is the case , replace that relay
the reasoning is this
there is a fuse for the coolant temp sensor
that sensor reads the coolant temp and reports to the ECM so that the air/fuel mixture can be adjusted correctly
there is a second fuse for the control for the fan relay
when the coolant temp reaches a set temp , the ECM through that second fuse energizes the fan relay which starts the fan to cool the radiator
from your description , the short is in that system and so I suspect the relay is faulty
take it to an accredited auto electrical specialist for a diagnosis of the fault

2005 cobalt put new radiator fan on still blows fuse even if the fan is not pluged in just hopeing someone had same problem with theirs


If you had a 5 amp fuse and fan draws 3 amps all is good.
BUT, if there is a short circuit before the fan, it will blow the fuse.
Check the wiring is not chaffed or worn between fuse box and fan, or switch to fan.

My radiator fan does not come on and the fuse inside fuse power distribution center keeps blowing, whats my problem also no radio..fuse also blowing


Unplug the radiator fan, replace the fuse and see if it blows again. If not, then its likely the radiator fan is shorted. Use an ohm meter and see what the resistance is. It should be greater than 5 ohms.

This just began when I got in my vehicle this morning. Yesterday there was no issue. Turn signal fuse keeps blowing. This also causes the heater/air cabin fan to not run though the heat does warm up. ...


its called a short circuit ,that fuse saved you from the fire.
all blinker wires can be shorted, in every inch of car, all 4 corners.
even lamps can short,
why not get car fixed, its a very simple common electrical problem.
most fuses on the car are shared,
no 100 fuses. is why. no room for the 100
that means you cant fix cars electrics with out a schematic.

login to mitchells diy
and read.
its all there. any time, on USA cars.

no the reverse switch is not , its wires are
when you go to reverse the switch closes and the 2 lamps glow
this closure IS a short but is 100% normal
what is not normal are the wires shorting to ground or the lamps shorted.
those old lamps can short, the large base bulbs do that

we find shorts using an ammeter.
inspections of wires.
and first learn what shared path is shorted first.
then bark up that tree hard.
