I had removed the original radio/single cd player and reinstalled the same radio the following day. The radio and CD player works great, however, the speakers on the left side (Drivers side) front and read doors do not work. Both speakers on the passenger side work fine. I first checked the BAL control and it is set mid way exactly on the vertical bar. Additionally, the Radio data system feature (RDS) only works for setting the hours and minutes on the clock. I removed the radio a second time and inspected the wire harness and the two plugs. Everything looks fine. I attached both plugs firmly to the rear of the radio and reinstalled it. The same problem exist. Can anyone help me. Thanks

 

Sounds like the speaker wires may be pulled out of the harness slightly.
