I've been retired for 8 years now. Almost went back in once in early 2002, but the family freaked out so I didn't. I miss my Marines from time to time, but 20 was enough. The last deployment was a NATO op in Greece and that was a nice finale.

O.K. I spent 7 hours on the Jeep today. I ended up replacing the radiator, water pump, temp sensor, serpentine belt & hoses. It "seems" better, but I still can't get the electric fan to come on. Is there a switch, relay or fuse? It never got over 210 idling with the AC so I think the radiator was the culprit. It was cruddy as heck. The one thing I didn't replace was the fan clutch as i was over $300 as it was and things are tight. If I think it needs it though, it is easy to do.

Thanks a ton for the help.

You said the electric fan did not come on,you said it did not get over 210,it proabaly did not get warm enough for it to,but if you were running the a/c it should have come on,did you plug it back in?

Yes, I plugged it in and ran the AC for a long time. The motor is good so it must be something else. I can hear the compressor kick on & off. Not too worried about it yet...

Did the fan come on before you started the repairs?If it did it is possible the sensor you replaced is the wrong one,I only mention this because whenever you turn your a/c on the electr4ic fan should come on,the electric fan is for the a/c first and water cooling second,I put the wrong sensor in another car and nothing would work.

how bout this question (1990 4.0) .. what does it mean when electric fan kicks on in mid winter, with heater on ? ... dont remember temp gauge being very "hot" either

it kicks in when ac is turned on also .. ac was not recently charged w/ freon, had a bit of cool feel when I got it at 108k, now im at 131k .. not hot enough in colorado for it in my opinion. my V6 jeep, I just removed that belt

also. sometimes the electric fan kicks in when I have the vent mode blowing

& why wont the heat come out of dashboard ?? just at feet . defrost

I can tell you that the electric fan comes on when it is needed for engine cooling,or when a/c is turned on. It is possible it got hot enough to come on,I know in Coloarado,(best state I have ever been in) it is hard to think that it could during winter,but it is possible. Your a/c must have enough charge for it to come on,as far as your goes,you must have a vacuum line off or the actuator is stuck. You will need to remove the climate control and look at it

if your clutch is kicking in and out then that means you AC freon sensor is good and sending a signal to the compressor but not the fan... check your fuses and change the ac relay... if neither of that works i would probly run a wire from the sensor to the fan and stick a bus fuse in between... that way what the compressor comes on... the fan comes on... maybe you positive wire is broke... also check and make sure the ground is good to the fan still... use a test light and clamp it to the positive on the battery and probe the wires going TO the jeep from the fan... one of them should light the bulb up... if not then you have no ground...

the electric fan comes on with the compressor... the compressor comes on when you switch to defrost... this way oil/freon is still pushed aroun the system keeping everything lubed up during the winter so when u go to kick it on for summer its not froze up... this is a good thing... most all vehicles do this...

the reason your panel registers do not open has to do with your selector is either bad,or there is a vacuum line off,you will need to remove your climate control selector to see which.
The compressor will come on when you select defrost,but the primary reason is to temper the incoming air for humidity control so it is drier not moist,if it had alot of moisture in it, it would condense on the winshield and inside windows,the air is always diverted across the evap but in defrost mode the compressor runs.
