It is the control module on top of the windshield wiper motor. The multifunction switch provides a specific DC voltage to the control module for each delay and speed.

Further testing would be necessary to determine the cause.

See first half of following video for access to the motor.

check the instrument panel fuse. when the vehicle is completely turn off and timed out. mine will draw about 200mA of current... I suspect the IP has fractured solder joints from GM using lead free solder, it does not hold up to vibration well at all. right now i'm removing the fuse when off... reflowing solder connections with real tin lead solder... so far I got my transmission indicator lights.

The controller could be bad but I would probe the related wiring first. From your symptoms it sounds like something can not handle the electrical load. You turn the F/R seat heater on but then you turn on the F/L and the whole system fails. It does sound like the source of the problem will be under the drivers seat. Testing needs to be performed to confirm and identify the source. Both seats share the same fuse and ground. This circuit may have a damaged wire or connector somewhere. Inspect and test as much as you can. Also look underneath the seats for anything. Customers are not aware that personal belongings and trash get pushed underneath the seats and will damage wiring. Also excessively moving the seat forward and back will weaken the harness over time. Please write back and let me know what you need. If it is more diagnostic information or suggestions just let me know. Good Luck

It is not necessarily the flow of gas that is important. You need at least 40 pounds of pressure for the injectors to operate correctly.

It should be on the inside of the rail on the drivers side, near the back of the engine, front of transmission. If it is not there it may not have one.

My 02 trailblazer pulled that stuff on me. Finally disconnected both battery posts, touched together for 60 seconds. Pulled both PCM fuses together, reinstalled, reconnected the battery and started fine. Gremlins at play I guess.

Have you checked the fuel filter by chance?

2004 GMC Yukon • Answered on Jun 03, 2017

Is it properly charged? A check of the pressures would be a place to look next.
