I have a 2010 Jeep Grand Cherokee Laredo. We tried 2 different after market stereos. Both times the Driver Side speaker will not work. All the other speakers work except just this one speaker. The kicker is that when we have the factory stereo in, all the speakers work. Any advice?

 

It might be a short, do you have a multimeter to check for one? Also, there is a separate grand cherokee forum page, folks over there may be able to offer more advice!
