in the bathroom we have a gfci outlet on a switch which operates two lights plugged into it. I plugged a floor fan in and it works unless I unplug the light unplug light and fan stops

Try moving the plug for the fan to the outlet where the light is plugged in and move the light to the one the fan was plugged in to.
Then unplug the fan and see if the light goes off.

wag, but the gfci outlet is bad and one half is being backfed thru the light load. ofc easy way to test is plug both lights back in and then unplug 'line side' light -the other light would go out as the fan stopped.

that has all been done at first it is in outlet with light, light is unplugged and fan stops, I move it down the line same gfi circuit with another light, unplug light same thing, took it into other bathroom with gfi oulet and same thing the fan does not have a light sensor

I'm getting confused. You said you moved it to another bath with GFCI and it worked, now you say "same thing" meaning the fan stops.

Is the GFCI receptacle a duplex receptacle (two places to plug in)?

Does the light have a cord that plugs into the GFCI?

If it is a duplex GFCI then do as I suggested and "swap" the light & fan plugs. Then unplug the fan and see if the light goes out.
Or do as jfletcher mentioned, plug in two lights (or 2 of anything) unplug whatever is plugged in to where the light was originally plugged in then see if the other item goes off or stops.

I'm trying to see if the GFCI is bad (mentioned by jfletcher), which sounds like it is if you have a duplex GFCI.

I've seen the neutral fail on the load side before and in your case it works as long as something is plugged in on the line side.

Don't you have a meter or at least a plug-in tester?

Why worry about a fan, you either have power or you don't at a certain location. If you don't have power it's time to trouble-shoot. You can do this with test equipment or just quickly swap out the GFCI. Make sure line and load neutrals are correct when makeing up new GFCI.

Now you're confusing me. How do you plug into the line side of a gfci?

poor wording on my part. gfci (especially older ones) can fail almost every way imaginable, and some that are head scratchers. by line side, i meant that only half the receptacle is hot due to failure (load side neutral is a usual suspect). as long as 2 loads are plugged in, they both work, but unplugging one (line side or better yet "still working half") can kill the other. unless half of the receptacle circuit is switched, which the op didnt mention. i dont see any other viable options, other than damaged fan cord/plug and coincidence with removal of lights/use as test eqpt. could be a good receptacle/bad wiring, tho if it were the lights would not work either.

eta: receptacle could have had line side hot/load side neutral landed on line side terminals or similar wiring error. older gfci do odd things when they fail. new ones just refuse to energize/reset

as far as troubleshooting, i would have already replaced the gfci. op needs at least a gfci plug tester to ensure downstream receptacles are protected; fans, lights, etc do not cut it here.

done that the light down stream always works with out the light at line side in, without anything in line side outlet, curling irons, hair dryers, etc., all work only fan does this

i dont understand how a hair dryer(basically a small fan+heater) would work and a floor fan doesnt, unless the fan is bad or 3 prong and there is something seriously wonky withe the grounding wire of that receptacle

eta: my motto with troubleshooting: eliminate the likely, easy, obvious and cheap first. What remains will give you grey hairs. yank and replace that gfci, (its a $15 part, not a $4000 breaker) make sure line and load hots ands neutrals are correct, no loose or burnt wires. try another floor fan

going to change but I was wondering why is it only the fan does not work? other appliances do thank you all of you for your help and I apologize for my wording

One really wild speculation: The two hot or two neutral contact surfaces inside the GFCI receptacle are made of one piece of metal which is currently acting like it is pivoted in the middle (because some of the supporting plastic is broken). The blades of the fan plug are thinner than other plugs or are completely flat and straight rather than slightly bent. The result is that the fan plug only makes good contact when there is a blade pushing back the other end of the metal piece in the receptacle unit.
Unfortunately this does not seem to agree with your observations involving a downstream receptacle. :(
