My 93 850 antenna only rises one extension,

any fixes???

If the lubrication trick doesn't work it could be a broken cable. It's easy to remove the antenna mast but a pain to remove the cable. You have to open the antenna motor to fish it out. Now that I've done it once I can probably do it in less than 15 minutes but I was paranoid when I did it the first time, I was worried the internal parts would pop out when I opened the motor.

Good luck.

The problem is super fine dust causing it to size up. the Wd40 is used until its flushed out--squirt- drip-squirt-drip-swing. Do it until it works. add no other lubs. see bay 13 for mechanics of removal/reinst

You could try pulling it all the way out and then lubricating with WD-40 although that may not last for long. Replacement is pretty easy.

yes. buy a new one. around 10-12$ on ebay

it could be bent as well, try putting a ruler or someting straight against it. that was my problem
