2005 GP GT. A few months ago, the door locks did something wonky like not allowing to lock with remote or even manually with the door lock button. Started the car, turned it off, tried the locks again then they worked and stayed locked. Has done that a couple times over the past few months. Last weekend we put in an aftermarket deck with a steering wheel wiring interface (PAC RP5-GM11) and not sure if it's a coincidence or not but a day after installing the deck, driving down the road and all of the gauges quit working (except speedometer) and the traction control light comes on also. We pull over, turn it off, turn it back on, and everything is working again. I disconnected the battery to maybe reset the computer but it has happened again. Anyone have an issue like this happen to them? I'm Googling and reading it could be the BCM going bad but then also read that the steering wheel adapter might be partially to blame. We tossed the OEM radio since the display lights stopped working so I can't put it back in to eliminate this possibility.
On edit: Does anyone know if we took the car to a dealer if they could hook it up to their computer to check to see if the BCM is going bad (stored error codes, etc.)?
