antenna not going up and down

I have a 94 integra gsr and yesterday, the antenna stopped going up and down when i turn the radio on and off, it is stuck about 1/2 to 2/3 of the way up. Any suggestions on how to fix this or were to buy a replacement antenna assembly?

try spraying the antenna with some WD-40 or other lubricant and then see if it will go up and down

sometimes rust can form in there and stop it from working

this morning when i tried to turn the rear defroster on it did not work, do you think that it could be something electrically wrong with it like a blown fuse?

its most likely a fuse

i just replaced the burnt out fuse and it all works fine thanks for your help
