FM and SAT radio, no AM

[perrya]

I finally got two possible causes as to why my 06 jetta has this issue. First, since the AM\FM antenna is in the rear window, upper portion, checking for continuity is one thing to make sure there are no disconnects. On my window, passenger side of window, it looks likes there are, but they seem factory made, the previous owner did have AM.

The second possible cause is the antenna amps which boost the radio signal. These are located in the C pillar and should have at least 5V going to them. if the AM amp has failed, the signal is not passed on.

Thanks for the update, if someone else has this problem any pics you can share might help them too

The amp is located in the c-pillar? That's never occurred to me. Thanks.

If it is the amp, the part will cost $140-175. If VW does the work, they charge $135 and hr! This is a good reason NOT to go to the VW dealer!
