The "open door with key in ignition" alarm is barely audible and seems to come from the left, front (drivers side--dash level) speaker. I can still hear the radio through the one speaker that is working, but is definitely annoying with rear passengers in ext. cab trying to hear something from the one tiny dash level speaker that works. The problem has moved around over time---certain speakers worked, while others did not, and they eventually quit working until I have what I described above. Cherolet makes a great 4x4 truck but obviously does not use quality parts in their stereo systems. I am not impressed! While very annoying and disappointing, I would like to get it fixed, but can't see the reason to do so since no dealership can tell me "Why" this has occurred in the first place. I have always owned a Chevrolet product from Impalas to Monte Carlos and Chevelle and have family members who also buy nothing but Chevys, however it may be a time for change. Our family has eight trucks and five/eight are experiencing the same problem. They bought after market sterios but I am not impressed with cutting out the molded speakers in the doors (asthetics) or wear headphones in a $37,000 vehicle. I just want it fixed correctly.
