The door chime i can barely here it ? Is there another adjustment somewhere besides the radio button # 6 to make it louder.... that did not work at all

I believe the chime may be tied into the radio, since the chime is heard through the drivers door speaker. Did you replace the factory radio? That may have caused it. Or if the factory radio isn't working it could be that.

It seems to me you should check your fuses, they burn all the time. There inside your car most of the times under or near the steering wheel somewhere in that erea

try this
disconnect battery
undo the fuse box and look at the wires behind that fuse you pulled

check that only radio and clock wiring are fitted there

the chime may its own power source

i could be wrong
i thought chime was separate to sound system speakers
and comes from a small but loud sound device on the instrument panel circuit board ..much like a computer

Even though it doesn't say locked, it probably is. Check your driver's manual to see how to reset it.

door chime is activatid by switch on door raido should only come on when key is in on or acc setting if key is not in all the way door chime should not come on at all

Some are on a button or lever in the door jamb and ford likes to attach them to the door latck in the door. A good blast of penetrating oil into the latch in the door will loosen it up.

Good news - they're adjustable. The radio is used to adjust the vehicle's chime level. To change the volume level of the chime, press and hold push-button 6 with the ignition on and the radio power off. The volume level will change from the normal level to loud, and LOUD will appear on the radio display. To change back to the default or normal setting, press and hold push-button 6 again. The volume level will change from the loud level to normal, and NORMAL will appear on the radio display.

Note: Each time the chime volume is changed, three chimes will sound to indicate the new volume selected.

Check the radio fuse. As unusual as it seems, GM has started having the radio (even though not turned on) generate the chimes and turn signal sounds. If the radio fails, all the chimes fail too.

This applies to other vehicles besides the HHR. My 2003 Silverado had the door chimes fade down so I could barely hear them. The fix was to replace the radio (under warranty, fortunately...).

You have a wiring harness problem
Take it to the dealer directly.......
