Why dont fans turn on?
I replaced the Fan Motor..Still does not turn on!
I heard it could be a bad Coolant Temp Sensor but wouldent that throw me a "check engine light" ?
What could be the problem?

Had a similar problem, replaced the relay, replaced temp switch, still no fans. Checked for voltage to the relay, found bad fuse link. Repaired fuse link, fans worked.

use a wire or something to jump the fan relay if they turn on ....then you relay is bad....i did this personally after i had to repair a broken thermostat bolt when my car started overheating check little stuff first such as relays , fuses and stuff
