On Friday I did install power antenna.When I try to raise the mast by pulling knob on the radio -mast didn't go up.I heard strong antenna motor clicking.I try to pull with plyers top of the mast and I realized that mast is going down while pulling radio knob.Looks like antenna works when going down but not going up.What is the problem?What I did wrong.I did replace cable connecting radio with antenna.I did connect blue wire with blue and green with green wire.Before restoration antenna was working fine.Maybe the knob on the radio that control antenna have something to do it? I did lubricate mast with WD-40.
what happens when you push the radio knob rather than pulling it?
It is only react when I pull up.
put a test light on the green wire while somebody pushes the knob, if it gets power, replace the antenna motor. if it doesn't then it is likely the switch inside the radio. could also be a broken green/white wire or bad connection at the firewall.
Pushing the radio nob in should raise the antenna when it is working correctly
I do think your new antenna motor is your issue
Motor needs to be working in both directions
Do be very sure your ground connection is cleaned and shinny metal but the motor is working —only not in both directions
The clicking sound is normal when the antenna is all the way down
The antenna is original from the car -not new.Maybe the radio knob I installed differently-because when I pull out the knob I have feeling like the antenna want to go down (it is already down).
"It is only react when I pull up." What does that mean? Are you pushing the radio knob in? The knob is designed to push in and pull out to raise and lower the antenna. Check the wire connector for a pin that has pushed out. The plastic connectors get weak and brittle from being exposed to the elements. It has happened to me before, that a pin pushed out of the connector when they were mated together.
Push nob —is up
Pull nob —is down
- Did you bench test antenna before installing? 12 volts to green pushes out, 12 volts to blue pulls in. If not, you can disconnect antenna connector at bottom right of firewall cowl and test via a 12 volt source to green then blue wire with antenna in car.
- Are you firmly pushing radio knob in? It takes some effort. Might take some tuner lube cleaner like the CRC sprays and push and pull the knob back and forth. If it is not pushing in and a spring action felt to push it back out something might be broken on the radio knob switch.
- Is knob correctly installed on shaft at the normal detente position with the Allen set screw?
- Is the connector at bottom right of cowl/firewall making good contact. Did you clean the metal inside the connectors to makes sure they make solid contact. It sounds like you spliced some wires... did you make sure everything was making good contact?
- And as noted previously, you can disconnect the antenna connector and test for 12 volts on the car side connector for 12 volts at green when pushing knob in, and 12 volts at blue when pulling knob out.
If you are pulling on the nob and the antenna is already down it is working correctly. ( on that side ) and will make a clicking sound when bottomed out
you need to get the motor to rise —when you push in the nob
Marks suggestions should help find the electrical issue and get the motor working correctly
Clean the mounting locations as they are the electrical grounds so clean them to shiny metal as that will make for good electrical flow to the antenna motor
When I installed the knobs on the radio I push the top knob too far and didn't let me use the function to push antenna up.
Thank you for all suggestions.
Yep, just got to let the knob set at that "detente" position when setting the Allen screw. Glad you figured it out!
Really nice job realizing the nob location issue was the problem
Where else could you ever get this kind of spot on repair info for such a specific unique repair
This place and the individuals ( you know who you are ) here are just the best for this type info ( repair ) for our year cars that is so very specific to just our year Cadillacs
Liked watching this difficult problem getting worked threw myself
