The engine fan in my Explorer keeps turning on for about 3 seconds and then turns off for about 4 or 5 seconds. It does it continuously whether I'm driving or parked in idle. It seems like something is wrong, because I don't remember it doing that before. Most engine fans run for about a minute or so before they turn off for a while.
There is a rather loud clicking noise that could be normal when it turns on and off, but the RPM's raise and drop as it happens when it's in idle about 2-300 RPMS. If I don't have my foot on the brake real good when I come to a stop my car will start to inch forward when the fan turns off. Obviously something doesn't seem right.
That and my airconditioning stopped working this summer. I think I need more freon or something. So I'm not running the AC, and that isn't what is causing the problem.
My car:
1993 Ford Explorer 4x4
4.0 V-6
53,000 miles on it
Any ideas? Is this something I should be concerned about??

No, no electrical work that I know about. The last 2 times I had it in the shop was for a new transmission (since the old one blew at only 51,000 miles going through the mountains of WV) and I had a seal replaced in my transfer case because it was leaking a little fluid. That's really it.

The fan uses a self reseting circuit breaker instead of a fuse to protect the circuit.
Either you have a faulty fan, or a bad breaker.
I'm leaning toward a bad fan drawing too many amps.

Did anyone do any electrical work to your truck? If so, they may have fouled up something under the hood. Also, it is possible you have a bad fan relay. If the relay is faulty, it may be dragging down your electrical system causing the slight increase in engine speed when the fan switches off.

the ac head psi is to high. start by putting ac gages on your system. watch the head psi if it just banks psi you'll have a resections in the system. most often its the orfis tube or the dryer/accumulator you need to reclaim the free-on and if the dryer has ice on it change the dryer and orfis.vac system charge the head psi should be about 200 to 250 @ 1500 rpms the low side should be 30 to 20

Rear-wheel drive cars with longitudinal engines usually have engine-driven cooling fans. These fans have a thermostatically controlled viscous clutch,you need to put a new cutch on.
