Hey Guys, I need some help getting my radiator fan to run. I've replaced the Relay and the fan switch. When I try to run a straight wire I blow fuses. I have powered the fan up using the battery so I know it works. I really don't know what to look for next. Any help will be very appreciated. Thanks.

Do you have power at the relay with the key on ? Are all your fuses good ? Does the fan come on with the HVAC control in A/C position ? Will the fan come on if you touch the wire on the engine fan switch to ground ?

Power to the relay? Yes
All fuses Good? Yes
Does the fan come with HVAC? No
Will the fan come on when engine fan switch is grounded? No

If you ground the green/white wire at the relay will the fan come on ?

No, the fan does not run when I ground the green wire - white line.

Hmmm, strange, is the ground off the relay grounded ?

What did you find?

I have a similar problem.
