My wifes power antenna on her 03 vert is stuck up in the up position. It makes a grinding noise when trying to retract. I'd like to just get it in the down position and just unplug it since she listens to cd's most of the time anyway. Any ideas? Happy Easter everyone.

I'd just take the whole thing out of the car (the power antennea) and get a short (like 6" or so stationary one) and replace it with that. That way in case your wife wanted to still listen to the radio occassionally she could but it really wouldnt be in the way or look bad. Just my opinion.

Mine was doing the same thing so I just removed the antenna's fuse from the fuse block on my 2001 Vert and pushed the antenna down and that's all you need to do.

I have no trouble picking up any stations with it down and if I want a short antenna I can just pull up just one or more small segments and push it down when I'm done.

TEXASCOUPE

Thanks. Thats what I was considering doing but wasn't sure if one could be installed like that.

TEXASCOUPE

That would work. Thanks. Wasn't real sure if you could just push it down. Suppose it won't hurt since its already broke. Is there anything else on that fuse that you know of?

RJRSW

No, just the antenna

It's minifuse number 24 behind the passenger side toe board

TEXASCOUPE

Great. Thanks for the info.

If I want to replace the motor, how do I get at it? Through the trunk or through the tail light?

Through the passenger outside tail light. I know this because the motor got in the way of me swapping out my rear side marker. I had to go through the wheel well as a result.

RJRSW

Both the trunk and tailight. The following is from the GM service manual and after you read this you will probably do what I did and just pull the fuse and push the antenna down:

Notice
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

I bought a replacement mast, but apparently there is a pice broken off in my motor. Thanks for the write-up on how to remove the motor. Does anyone have pics that would accompany the instructions? I also read somewhere on the forum that I could remove the plastic rivets and remove the broken pieces. I would have to replace the rivets with screws. Anyone know what size/lenght screws would be needed?
Thanks,
Greg

This is great information since mine does the same thing. Before I buy just the mast, I wanted to get it out and make sure that's all it needed.

My question on the quote above, do you have the instructions on that panel removal because I've looked at it and I see no screws, snaps or anything else holding it in. I'm very hesitant to start yanking on it for fear of breaking something I shouldn't.

Also, I read somewhere that you can pull the passenger side wheel and inner fender to get to the antenna. Problem is I can't find that again and I'm not sure if it was for a C5 or other.
This process looks more feasable because you can see all the screws holding in the inner fender.
