'96 maxima radio antenna question

The power antenna on my wife's '96 Maxima takes forever to go up or down.

Do I need to replace the whole power unit with mast, or will just a new mast
fix the problem.

Not sure what the problem really is, but I bet it is somewhat common in this
age Maxima.

Have you tried lubricating the mast? Spray some WD40 on it and cycle it up and down.

If 'OKC's lube idea doesn't work, the answer to your replacement question is, could go either way. Some vehicles you can simply buy a replacement mast with the plastic ribbed tailpiece that runs in & out of the motor housing and on other vehicles the mast isn't available separately. Likely a dealer item either way, so give the Nissan guys a call and ask the parts department.

You can get just a mast for your Max, it's easy to replace.

Yes. Power units and masts are plentiful on Ebay.

What I'm trying to figure out is whether it's a mast or power unit problem. Seems like it wouldn't be a mast problem, since it does still go up and down.

Not sure it's a power unit problem since I can hear motor run while the mast very slowly goes up and down.

There's some kind of problem, as the mast up/down function was quick and vigorous awhile back. Now it's a groaner and slow as molasses.

The thing about the WD-40 is a great idea. I'll try that. Thanks.

My guess would be that the teeth are worn, either on the mast tailpiece or the actuator gear in the motor assembly, so that you can hear the motor running fine, but the gear/teeth interface (how's that for a fancy engineering term) is essentially "slipping". I think you're going to have to pull the assembly out for disassembly and inspection to determine if just a replacement mast will do the job.

The WD-40 might make the whole discussion moot, of course; may just be too much friction somewhere in the works and a little lube wil free it up.

If your antenna goes all the way up when on and fully down when off, then the problem is not the mast, more likely the motor assembly is. If the antenna does not goes all the way up when on and not fully down when off, then the mast is the problem.
