    fan wont blow until 10 mins after start, if then, or may blow right away/2002 GC 4.7

    Hey ya'll. Got an 02 Grand Cherokee Limited, 160k miles, has the 4.7 ltr v8. I have an intermittent problem with the fan blowing only when it wants to. After start up in morning it wont blow at all. Heat is trickling out and 10 mins later when fan does decide to blow, everything seems fine. Same with the A/C. Could it be a bad resistor and if so does anyone know where its located? Or is it something else going on maybe? Im not as familiar with Grand Cherokee as I want to be. Oh yea, I just had a new heater core installed 4 or 5 months ago if that helps. But heat is hot, its just the fan not wanting to act right. Thanks a lot!

    kinda sounds like a loose wire connection somewhere. if the core is new id start looking there at the wire hook ups.
