Impala Going Haywire
I drove to work yesterday morning - nothing out of the ordinary.
When I left in the afternoon, however, I noticed that on the drive home, the Impala (2001) was acting VERY strangely..... Doors would lock...then unlock...trunk would unlock..."Security" would display..."Service Vehicle Soon" would display...the "Battery" icon would display...interior lamps would flicker on and off...and the air conditioner would eminate hot air. All of the aforementioned would repeat over and over the entire trip home. Because of the nature of some of the above actions, I suspected maybe there is a malfunction with the remote keyless entry device. Upon return home, I removed that device and with ONLY the key in my possession in the vicinity of the car, I started it. All was normal. No warnings, no bells, no flickering, and even ice cold air from the air conditioner. To see if I could reproduce the situation, I then retrieved the keyless entry device from the house and brought it to the car, started it, and the strange behavior returned. I then reproduced the scenario with only the key, and all returned to normal. I then figured that I simply had to discard the faulty keyless entry device. This morning, I worked from home, and my son took the car to work. Upon his return home, he mentioned that the car was acting very strange (same activities described above). I then informed him that he must have used the wrong set of keys since the one keyless entry device was faulty. I then used the car later...using ONLY the key...I did not have any keyless entry devices in the area...but the car acted very strangely again. It seems NOW that perhaps it is NOT the keyless entry device but something within the vehicle. Even when I turned the car off, the strange locking/unlocking behavior would continue. I finally disconnected the battery for a short while, then re-connected it. The strange behavior stopped. But, once I re-started the ignition, everything resumed (flickering, bells, warnings). My question is whether anyone had experienced such strange behavior by their vehicle and whether you know of any cause and/or resolution. Thanks. Richard |

Check for a bad battery grounds first, then suspect a possible ign switch

Replace the Body Control Module (BCM). I had the same problems, replaced BCM
and problems gone. About $190 in parts and whatever your dealer charges for an hour of labor. It is located under the dash on the drivers side. The box with the large wiring harness. It controls the majority of the electronics in the car. Common problem.
