OK, I'm looking at a diagram of the power distribution center which is where your relays are located. I was incorrect last night in my assumption of the fan relay location. On previous models they use a relay that is mounted to the frame rail but in yours there are two relays in the PDC. I will gather some more information today and help you out this evening. If you need help sooner then I will opt out and your question will automatically be resubmitted for another expert to assist you sooner. I can keep tabs on how you'd like to proceed, but I can't get a lot of time to help during today, it's been real busy at work.
You should get an email each time I respond to your question.
Robert, thanks for hanging in there for me. I've been thinking on this off and on today and wanted to verify a few things.
-2004 Jeep Liberty, 3.7L Gasoline Engine
Is your complaint the check engine light coming on or an overheating condition?
Also, I looked over the 03 and 04 wiring diagrams for the radiator cooling fan and both show the ground for the fan being on a Black/Orange wire at the fan. The power for the 03 is provided on a single wire that is yellow. The 04 year model gets power from the low speed fan relay on a Dark Green wire and the high speed fan relay provides power on a Yellow wire.
I'm trying to verify your concerns but also verify what wires you are working with because they don't match things on my end. Let me know what you can come up with and I'll be ready to help some time after 6pm.
Robert, thanks for the accept. From what I'm seeing there were two responses that you "accepted" on 12-31-09. Please don't click accept anymore unless you feel the need to, according to what I can see, I did get paid and really appreciate it.
Were you able to fix your jeep with the information we gathered while working on it?
Thanks for the update Robert. Let me know if I can help in the future.
