Intermittent Fan...

98 xj. All of the searches i did seem to focus around the fan cutting out, and then no more air coming out of the vents, going to the defrost vents(vacum related). Mine is a bit different. Last winter I had no problems, blasted heat all winter and barely noticed the fan coming on. Spring rolled around, and knowing that my AC did'nt work, I put a full charge in it. Worked for a couple months pretty well, but slowly became less cold air, probably a small leak. Then one day I turned on the AC and noticed the fan coming on and then shutting off about every 5 seconds. Said F it, and didnt use AC anymore. I had to use the heat the other night and it is doing the same thing, 5 second on, 5 seconds off, but air is still flowing well through the vents. It doesnt matter if I am idling, cruising at 30 or 75, It is always doing it.
Any ideas? It's really annoying, plus I would really like to avoid burning up the motor. Thanks.

The fan for the radiator is suppose to cycle on and off.

should it be cycling at that rate though? I have the exact same issue, I didn't notice it for the first 4 years of ownership, it came to me in a traffic jam and it was truly annoying. It was like clockwork, 5 seconds on/off. After searching on this I just chalked it up to it being the normal cycle period and I just didn't hear/realize it until later. Kinda like when someone points out a leak in the faucet and from there on out can't get it the dripping out of your head.

It is annoying to the point where I severly limit my use of the AC because of it....though I annoy easily.

It has been 2 years since I have noticed this, all works fine however I have always had the question in the back of my head if it was indeed normal.

It can, depending on outside temp.If it don't need to run long thats a good thing.
