Antenna motor has a very loud grinding noise. Antenna won't go up or down

There are a few possible reasons why your car might be producing a very loud, continuous sound that can only be stopped by disconnecting the battery. Some potential causes include:
1. A faulty starter motor: If the starter motor is faulty, it can cause a loud grinding or buzzing noise when attempting to start the car.
2. A malfunctioning alternator: If the alternator is not functioning properly, it can cause a loud whining or grinding noise.
3. A stuck fan belt: If the fan belt is stuck or has become worn and is slipping, it can cause a loud squealing noise.
4. A stuck horn: If the horn is stuck, it can cause a loud, continuous honking sound.
To determine the cause of the loud noise, it is recommended to have the car checked by a professional mechanic. They will be able to diagnose the issue and suggest the appropriate repairs. In the meantime, to stop the noise, you can try disconnecting the battery as a temporary solution. However, it is important to identify and fix the root cause of the issue to avoid further damage to the car.

Losing the bearing in the blower motor maybe.

If it is an automatic transmission, first check the fluid level. If it is low, fill it up and try it again. If the level is fine, then there is a bigger issue and you should seek a professional's help.

The antenna cable/regulator is usually made out of plastic with tiny slots that engage the antenna motor gear. When worn, they make grinding noises and usually don't retract or extend all the way. There is no quick fix for this; replace the antenna assembly.

Yes the motor can be unplugged, the plastic gears in those motors have a tendency to wear out.

the computer is bad and also these cars are known for the insturment clusters to go bad along with the computer. get them both fixed and it will solve your problem.

do you have a broken power antenna?if so the antenna motor is making noise with the broken antenna mast-if it is not related to the antenna-need more info.on what kind of noise you are hearing

The gears are going out in the motor. If the antenna goes up and down, then the gears have corrosion. If it does not move....then the gears are toasted or the antenna cable inside the housing is broken.

Try jacking your vehicle up and turning the tires. listen for any odd noise like a grinding sound, wheels hubs have been known to make a grinding noise when they go bad.

my antenna just stopped working in my MR2 2003 Spider. The motor still runs but the antenna will not go up and down. It made a weird noise and I had to pull the top of the antenna up to stop the motor from sounding loud.

Should I replace this or can you disconnect it and push the antenna up and down?

Thanks
