I pulled out a previously installed Raxiom system and installed the OEM unit. Previous owner did it about 4 years ago. The speakers worked fine but with the OEM back in, the drivers door speaker does not work. No wires were cut. This was a plug and play install. Does anyone know if something has to be programmed to get the OEM system working again? I still have a year left on the warranty, and intend on dropping it off at the stealership, so I was meticulous about getting everything back to stock.
