Do you have coolant in your cooling system?

Same thing just happened to my GF's Liberty - turns out the fan wasnt working. Replaced that, topped off coolant and AC - good to go! ;)

You mean that the fan doesn't run when you switch the AC on?
Is the AC compressor running when selected on? There should be a certain minimum pressure in the system to be able to get the AC compressor working. Maybe its time to take it to a specialized AC shop and let them check the system for leaks and put a fresh gas charge in it.
Does the cooling fan work normally when the engine is hot and the jeep standing still for a while?
Just seeing now the header where you mention OVERHEATING:o.
So how did you check the relay? I'm not familiar with the Liberty cooling system, but if the relay and the fan are ok, it could be a temp sensor or wiring.

It is full of coolant, when i started it this morning the radiator fan came on and air was blowing cold, now radiator fan not on and blowing hot air.. Checked the fan jumping it from the pins to battery, checked the relay's from switching with one I knew was good. I have no idea what it is...And yes I am a female but know a little about cars.. Thanks for any ideas....

At that point - id check into what Frango suggested - temp sensor or wiring.

So if it is the temp sensor that would make the radiator fan only work sometimes??

If I take and have a diagnostic test done on it will it throw me a code???

Your issue seems to be electrical - I have no idea where exactly - that's where you come in :) We can only suggest possibilities :)

It would only throw a code if the temp sensor is COMPLETELY dead (I believe). I dont think partial working will show you anything. On my GF's fan being dead, we didnt have any codes - i checked.

Good luck :thumbsup: You might want to wiggle some wires and see what happens. I have a service and repair manual (PDF), but it's 66Mb. If you want to PM me your email address, I'll be glad to send it to ya :)
