my gf has a 2004 3.8l v6 with a wierd problem. the electric fan isnt coming on. the temp meter runs to half way point and a little past an it dosent come on. i already checked fuses and replaced a circuit breaker that is supposed to be for the fan and still nothing. the fan however does work because i tried to connect it directly to a battery and it worked....any ideas? is there some sort of thermostat switch or something?

 

there should be a relay

 

Does/has the car overheated?

 

the car hasnt overheated becauase we turn it off once we c it get passed the half way mark on the temp gauge, and i looked on the manual and it is a circuit breaker fuse that it codes for for the fan. if it was one of the major realys wouldnt it also effect other functions as well?

 

The temp sender may have failed

 

If I remember correctly, turn the AC to MAX and that should turn the fan on. If it doesnt work, take that with a grain of salt because it never worked on either of mine (95, 96) :P

Being a 2004 it has two sending units if I remember correctly (Theres that phrase again :P ) one for the guage cluster and one for the ECU.

My 2000 3.8L that I bought has two sending units where my 95 and 96 only have 1.

 

I had the temp sending unit on the driver side head go out/i broke it and the fan would come on the second I cranked the car and stayed on until I turned the car off.
