What is this?
Radiohead, I have power to the blower motor when the ignition is on (low speed only) Is there any other power source I need? -

What is this?
when I removed the old wiring, there was a wire from the right side of this block that went inside the cab and connected to a resistor type connector mounted to the steering shaft. From there, 2, three wire bundles were just laying inside the dash not connected to anything. From what I found... -

What is this?
I rewired my 77 K10, but the kit I used didn’t have the new wiring for the AC/heat. I used my existing wire, which is what the instructions suggested. My problem is now the blower motor will only work on low speed. It comes on when the ignition is turned on but will not speed up with the... -

What are these things? Overhead heat/air system!
My truck don’t have any power to the doors, but maybe it was wired for it. I’ll hang on to the harness but I’m not planning on using it. Thanks,- Woodhook

What are these things? Overhead heat/air system!
It’s a truck. The vin plate on the door jam is hard to read. I’ve looked at my insurance papers and tried to search for the correct data, but nothing will come up. I can see the words “camper loading data” on the plate, not sure if that is on all the square bodies. One other thing I found out...- Woodhook

What are these things? Overhead heat/air system!
I’ve searched the light duty truck service manual and I think this is the wiring harness for the overhead heat/air unit in suburban models. It makes sense that the 3 connectors on one end of that harness pictured are exactly the same as the other end. The overhead unit has two blower motors...- Woodhook

What are these things? Overhead heat/air system!
I went inside the truck and removed the other relay/breaker and I plugged both of them in the wiring harness where they go. The little wire on the right is the one that connects to the engine side of the firewall. The rest of these are inside the cab. The two ends of this wiring harness are...- Woodhook

What are these things? Overhead heat/air system!
The little relay/breaker hanging down on the left picture is actually the same silver relay/breaker in the right picture, installed under the dash. I'm going to remove the heater/ac control and see if the ends of these wires would connect to the fan switch. I'm sure I'm going to have to...- Woodhook

What are these things? Overhead heat/air system!
I will add 2 photos that will show my problem. The small wire connected to that block, comes from the air conditioner and then goes through the firewall and connects to these two resistors/relays/fuses, (whatever they are) above the brake pedal. I've already installed a new wiring harness and...- Woodhook
