This information is being provided to help others who also may have been scratching their head over relay locations on models after 2003.
I am also am in need of help.
Online seems to suggest that the relay is located here, however it is not located there on my 2004 !
FSM lacks information about fan speeds, and now I am wondering do I even have a 2 speed fan?
If the relay is not on left side as first photo shows, now where is it located?
As you can see above ^ one cartridge fuse and 1 hi, and 1 low relay is shown, is in under hood Dist Center.
So I suppose that the PCM now controls the fan & speeds.
Can someone read this 2004 wiring diagram, this does not look right, does it really show a 2 speed fan set up?
Now here is the 2005 diagram & it shows the 2 relay design. I have an export Canadian 2004 model..wow confusing!
Me think my jeep made in May of 04 and they are publishing old information, as in not updated yet to the FSM of a 2005.
Even at 235F, the fan does not seem to go into high speed, only low speed ??
What is the difference in rotational speed suppose to be?
I assume it should be much louder on high?
How do I force a test to see if I have high speed working?
Possibly I should replace the coolant temp sensor & see what happens?? !!
