Question about Hyundai Motor 2002 Sonata

1 Answer

Power Antenna gets stuck; Motor makes noise while going in/out

* Hyundai Sonata 2005
* Antenna does partially come out and also partially retract; neither ways is the movement full. When the antenna stops moving either ways, there is a heavy knock each time, almost like the motor tries for a few seconds, and then misses a thread and hits the next one.
* No clue on how it started or how I can cure it.

Any help would really help.

    Sorry, the model is a Hyundai Sonata 200, NOT a 2005.

    The noise are broken gear teeth inside the antenna motor housing. I had the same problem. You need to patiently dismantle find the broken gear and hunt for a replacement or buy a new rebuilt or new housing.

    Rebuilding the antenna housing is not fun if you have a schedule, I put it off for over a year. The whole job including finding parts can be over a week. Once you determine which gear is broken and find it, you need to refurbish with new parts and re-install the motor and then snake the antenna mast (look for directions). It took me several tries to get it right but I now feel reborn.

Back drivers side window is stuck down

Could be almost anything from window motor to wires to relay to window button. You could start at the window button and test power to motor, then eliminate relay until you find where power is out. If power is going to window motor and it does not work, its a bad motor.

Glass shops can fix this for you.

Car makes a big clunking noise when you first start to move

Hyundai Sonata is a front wheel drive.
When moving in a straight line,the noise will be from motor mounts,transmission mounts and stabilizer support from the top / front of the engine.
Inspect for rubber bushing ware and loss mounting.
Lift up the vehicle with jack stand or a shop lift to give a better view of the worn parts.
Check the CV plastic boot axles.
A worn CV will make noise on tight turns.

I am replacing the power antenna mast on a 2005 hyundia sonata...I have turned the radio on but cant get the cable of the portion of the old broken mast to come out

You need to remove the top cap cover, this is the ring on the top of the antenna that holds it to car then use some small needle nose pliers to pull the rest of the mast, if theres a broken part stuck inside then you will have to remove the ant and open the side to remove the rest of it, then reasmeblt unit and put back on car then slide new one in and have someone turn radio off as you feed ant in, if it doesnt go all the way in then turn radio on but dont let it come out then turn it back off fast and feed the rest of ant in, once its in place install the top cover ring to lock it in place. hope this helps.

1991 Chrysler New Yorker, FIFTH AVENUE. Power Antenna stuck.

sound's like the motor is bad if you have someone turn it on as you stand by to hear the motor kick on would be the best way to know. if it is a good motor it is off track if that's the case turn it on and try to get it with a pair of needle noise pliars and pull it out.

Antenna on 2005 sonata does not raise up when turning radio on

Keep it simple first, check the fuses. If they are good check to see if motor is getting power. May have a bad relay.

Power antenna wont go down

The flex drive cord that raises the antenna mast and lowers it is most likely broken, you can replace just the mast and drive cord.

Power antenna does not go all the way up, does not power retract

Does the motor continue to run even though the mast doesn't retract? Is there a loud 'click - click - click" as it tries to retract and extend or more of a chattering noise? Did you clean and lubricate the spool into which the toothed belt goes when the antenna retracts? Use an all weather grease (white lithium). Did you clean the teeth on the gear that drives the belt? There is a small metal guide where the belt meets the drive gear, sometime this wears and allows the belt to slip on the gear. Pull the giude straight out, then rotate it 180 degress and reinstall.
