Click here and you will find instructions for removing the radio module and for replacing the radio module capacitors.
I replaced the capacitors in my radio and it stop popping a clicking noises.
To see if the capacitors are your problem do the following:
1. Park the car outside so your house electrical system will not effect the test.
2. Press the 'Radio" hard button on the upper right of the CRT screen.
3. Press the 'Tune' soft key right on the CRT. (tune buttons will appear at the bottom of the CRT.
4. Use the up and down soft keys to tune the radio to a frequency where there is
not a station and does not have static if possible. Steady white noise is ok but silence is best. (may be hard to achieve inside a city).
5. Turn up the volume and listen for random pops and clicks.
If you still hear the pops and clicks the capacitors need to be replaced. Otherwise check for bad speakers, bad antenna or bad connections.
