Cooling fan wont turn on

hi,

My engine cooling fan wont turn on at all.
I let the car idle for awhile and when the temp gauge gets to almost the redline it still wont turn on.
Coolant starts bubling in the coolant resevior.
The only way im keeping it cool now is by just driving and letting the radiator cool it.
I checked the fuse and its not blown.

Thanks

1. Fan Relay
2. Coolant temp switch
3. Fan motor

Those are the 1st 3 things I would check.

if worse comes to worse just rewire your coolant fan to a toggle switch

first test the fan motor, take it out and hook it up to a 12v power source, if it spins then the motors good. if its good, its probably the relay because those are the ones that usually go, not the coolant temp switch. but both could use a replacement anyways so if you replace the relay and thats not it, it was good u replaced it anyways because its old

check the fan plug....sometimes it gets corroded... just check it on a 12v souce....toggle is a good idea.
