Speaker on left door worked and next morning not working..

Probably the driver door speaker is going out (yes the "click" noise is "played" through the speaker). Seems common on these cars and was my problem. Turn all your music to that one speaker using the radio controls and see if it plays music. All the chimes and blinker noises come out of that speaker.

The chime system is a class 2 databus. The chime is actually created by the factory radio and plays thru the left front speaker. If the radio is non factory and the appropriate kit was not used ( which has a speaker for the chine) or the front left speaker is blown then you won't have a chime. If you do have a factory radio and the speaker plays the music fine then the problem lies in either the data circuit or the radio. If you have an aftermarket radio and the correct wiring kit was used then either there is a bad connection, blown chime speaker or defective kit.

With the radio on, make sure there is voltage at the speaker wire positive and negative leads. If there is no voltage, the output from your receiver might have gone out.

all speakers r connected to the same wires on the radio
If left/right balance and front/rear fader work properly
and sound is coming out it is likely (but not definite) radio is ok and speaker wiring is the issue.
HOWEVER, if it sounds the same on both left and right, it could be the radio. It is unlikely both sides have the same issue at the same time without it being in the radio.
The only way to verify it to disconnect the speaker and substitute a known good speaker.
So back to troubleshooting.

Below is a listing of the radio wires and what they control.

The door chime is played over the speaker. I had the same issue the speaker was junk. The circuit resistance was correct but no tunes. Replaced the speaker with one from the junk yard and sounds great all the time.

I had the same problem. It is probably the laser reader for the CD player. I took it in to the dealer and was referred to a vender as the warranty had expired. I took it the vender 10 days ago and just had it re-installed today. Works well. BTW, the dealer took it out and send it to another company which repaired it and sent it back.
