if you jump it it should run but check the fuse underhood and the relay which is behind the bumper fascia at rh headlight as well as ground.

actually ours says green but due to age it can be blue due to fading if you ran it direct and it didn't run then it's probably the fan. see if you are getting power from relay. you can always put an aftermarket fan on instead of a factory one. rock auto has factory ones from $47-120 take your pic.
