Bad motor for screen

Same as with all vehicle issues

Check the fuses

Then get out the Wiring Diagrams & get familiar with the
system & pick a test point, or start taking things apart, to get
to the motor or your test points,the most logical part to
have possibly failed

No one can do that for you or tell you what the problems are

Always need a vehicle to test

Someone would need to check the blower motor and the resistor for voltage and ground.

You have to check if the starter solenoid is bad. To do that you have to locate it, then put a screwdriver across the positive and negative terminals. There will be sparks, so don't panic.
If the starter spins, you have to replace the solenoid, if not then try jump starting the scooter with a bigger battery; yours might be bad.
If that still doesn't work, you may have a bad starter motor, loose wires, bad starter relay, blown fuse or even a bad brake switch.
- but first try to start again and again - sometimes it starts after several attempts....

Is your kill switch off? And sometimes the buttons get dirty and some contact cleaner flushed through them helps get them working again.
NOTE Make sure the contact cleaner is safe on plastics. Radio Shack has it on the shelf.

sounds as if the motor went bad

sounds like a bad swich. but since it all of a sudden quit on you the blower motor could be bad as well. you can connect power and ground to blower to see if it works. if it turns then the swich is bad.

Sometimes you have to unplug it for about 30 seconds, then when you plug it in press the power on button. If there is still no sound, check the speaker connections on the back they sometimes come loose.

sounds like motor is overheating,if capacitor is faulty this could be cause,the microfarards should be as per whats on side of capacitor,or motor could be bad ,most motors have a thermistor which stops motor from running if it overheats,next time it happens check if the motor is very hot ,be careful it could be very hot,make sure unit is switched off,also could be an overheated mains wire but usually fuse blows in this case,hope this helps

Sounds to me like its time to go to a service shop and have your AC recharged, it could be that the amount of refrigerant in your AC system is low, possibly depleted. I would go have that checked out, there is not much that you can do personally unless you are liscensed to handle/recharge refrigerant systems, if in that case your in luck.
