The code P0674 tells you that something in the glow plug circuit is faulty causing the glow plug on cylinder #4 to fail to heat up. The entire circuit must be checked to locate the fault.

Symptoms With just one glow plug failure other than the check engine light coming on, the symptoms will be minimal since the engine will normally start with one bad plug, under freezing conditions you would be more likely to experience hard starting.

Potential Causes The causes for this DTC may include: Faulty cylinder #4 glow plug Open or shorted glow plug circuit Damaged wiring connector Faulty glow plug control module Diagnostic Steps & Possible Solutions You will need a digital volt ohm meter (DVOM) for the complete test.
Continue through the tests until the problem is confirmed. You will also need a basic OBD code scanner to reset the computer and erase the code. Check the cylinder #4 glow plug by disconnecting the wire connector on the plug. Place the DVOM on ohms and place the red lead on the glow plug terminal and the black lead on a good ground. The range is .5 to 2.0 ohms, if it is out of range replace the glow plug.

I strongly suggest you contact a local dealer, I have never seen this symptom on any GM vehicle. I think you have a loss of battery power for some reason or a faulty ground, where that may be is another story.

Your wiper motor has shorted out and needs replacment.
In order to find out you need to disconnect the wiring from the wiper control switch,with the ignition on, if the wipers stop then you need to replace the switch.
If the wipers keep running, then you have a defective motor, replace the motor.

Make sure your brake lights work.
May be bad switch,the cruise control runs through the brake light switch by the brake pedal.

Remove the door panel. There will be several screws to remove, look for plugs in the door, screws will be behind them. After that lift up on the panel, if it doesn't lift, then insert a screwdriver at the bottom of the panel. It pops of, be prepared to buy some door panel plugs. They break. after that you will see how the cable runs and be able to remove the bad part. Not all cables break.

I had the same issue on m dads 2005 Z71. It wound up being a bolt fell in the track of the seat and skint a wire and grounded out. resulting in a blown fuse and seats and all windows but the driver window quit working. Also check the connectors under the seat, some of them can be seperated just enough to cause a power problem
