Hello! I have a 2007 GP GT and it had an exhaust leak, so we welded it to fix it. I'm aware that welding can cause damage to electronics, so I was sure to disconnect the ground terminal from the battery before welding. Once we got done the stereo and blower motor no longer worked. Upon further investigation the stereo has power to the continuous wire but not to the remote wire, even when the ignition is on. The servos for temperature control and vent control both audibly move when adjusted, however the blower speed control does absolutely nothing at any setting I have of course checked all the fuses I can find. Does anyone have any suggestions of where I can look?
