2004 trailblazer fuse box picture - 2004 Chevrolet TrailBlazer

There isn't a fuse. There is a circuit breaker, but it runs all the windows.

The "rear" fuse box/panel isn't below or under the back or rear seat. It's basically located behind kind of underneath the drivers front seat. Just remove that cover in the picture to expose the fuse panel.

If the tail light fuse is good, I would check the headlight switch for power on that circuit.

I looked in mitchell service information, what engine? 4.2L 6cyl, or the 5.3L v8? Mitchell shows a fuse box under the hood, and an addittional fuse box located beneath the 2nd row seats. I could not find a fuse that is dedicated to the heated seat function.

Front fuse box



Rear fuse box

Sounds like a fuse. Are you getting power to the driver door module (control cluster as you say). Below are 3 pictures for you. The first one is the location where the fuse box is located for that fuse (under drivers seat in the rear). The second picture is a diagram or the latout of the fuses. The fuse you want to check is the fuse marked "LT DOORS" or the one marked 02. It should be a 25 amp fuse. The 3rd picture is a wiring diagram for the circuit. If the fuse isn't blown check the power wire from the fuse box to the driver door control module. Sounds like a power issue. Anymore questions or diagrams that you need, feel free to email me at [email protected] and I should have and will send if you need anything else. I hope this helps and good luck.

if it does have a fuse for the trailer lights it will be located in the fuse box under the hood

I have front and rear a/c. The air is blowing in the back but not in the front. Don I have 2 blowers/units. Could this be a fuse?

Have you checked the fuse box under the rear LH side chair?? This is where the fuses for the outlets are. Hopefully this helps

There Should Be On Under The Driver Side Dash.
