Fan stopped running. It will move only on turbo and stops after 15 minutes. Compressor fine. Seems like it needs oil. I took the front off but i am puzzled on how to oil and pull the insides out without taking the whole thing out of the window.

Could be lack of service. The unit depends on a clean evaporator and condenser coil. The "other" motor you hear is the compressor starting or stopping probably due to either a high pressure or low pressure switch, or thermal cut-out.
be aware that not repairing this asap that you are causing yourself more problems First I would change out the fan capacitor and see if this could be the problem. Secondly if the capacitor isn,t the problem change out the motor . By continuing to allow the system to cycle like this the compressor will take a dive on you costing more . Good Luck
If a fan motor quits working during a cycle it usually means that the thermal protector is turning it off. If you had an amp meter on it, you would notice that it is exceeding the listing on the nameplate, Nine times out of ten this is irreversable, the motor needs to be changed. Sometimes if there are oil ports on the motor, you can add a few drops of zoom spout oil and that does the trick. But usually the motor is already damaged. Good luck.
The fan motor is getting hot and going off on the internal overload in the motor. This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor. To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok. To check the capacitor you will need some kind of tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much. To check the voltage you will need a voltmeter and measure the volts at the unit.
eventually,cycling process is doing done if the thermostat sense the configure temperayure set up it will trigger to stop your compressor motor as well as the blower fan,blower fan independenly to you compressor.if your thingking that your compressor is tripping off,check your operating current on one line using clamp ammeter and compare to the rated current that tag on
motor compressor body,if the current flow is higher than the rated current specified on compressor motor,well problem occured it will trip your compressor,because overload protector is becoming your thermostat.but if you got same current result it was cycling process.If tripping off maybe air is present in your system call qualified ac tech, to purge out air in system.
Have someone check the run capacitor of this unit. If the run capacitor is bad over shorted it can cause the unit to run and short cycle on a current overdraw. This makes for an electrical imbalance in the compressor motor. Next step is the compressor is faulty.
