I'm missing the lower contact that the contact plate rides on at the base of the steering wheel. I can't find any diagrams online or information about what is actually supposed to be there. Can someone let me know if its a spring contact or a roller? All I have is a hot wire for the horn that appears to have been cut and the hole that holds the contact is empty. If someone knows a part number that would be even better.

I’ve got a CV713 and the Jake brake doesn’t work. The check transmission light stays on. When I press the cruise set switch it gives flash code 35. I’ve seen multiple different meanings to this flash code like Jake solenoid 1 and park brake sensor. Can someone validate the meaning of the flash code and if it’s the park brake sensor, where is it located?

Well I found the inline fuse and it is not blown. I also made a new discovery. Vise grips holding the heat damper closed instead of it being connected by the thermostat push rod behind the cup holders.

After googling. I did check this not knowing the name of it. It also was showing 12v at the connector and also caused the fan to kick into high speed when the connector was disconnected.

Im not sure where the binary switch is to check this. If you let me know where that is, I definitely will. I'm going to check the charge today and if it is empty, I'll start leak testing to see what else may need to be replaced.

The AC dryer does have 12v going to the sensor connector. Validated that yesterday as well. When the connector for the dryer sensor is disconnected the radiator fan engages high speed. I will try to find an inline fuse. I followed the wire back over the top of the engine until it drops out of sight behind the motor. I didn't crawl under the truck to continue following it yet. The wire didn't have any damage to that point at least. I have not checked the charge yet, just spent a little time yesterday with the volt meter checking electrical signals to start the diagnosis. I bought my truck from an auction and knew I would have problems given the price I paid. I'm assuming the AC clutch should at least attempt engagement when 12v is applied but makes no noticeable attempt at engaging. The truck has a salvage title but does not show signs of being wrecked. The electrical issues seem to be the main problem so far. Trailer ABS Relay in the engine bay is blown open exposing the copper coil on the inside of it. I have new relays arriving today. There was another ABS fuse on the inside panel missing I've tested all the other fuses and circuit breakers and have found none of them to be blown which is a good sign. The fuse I added to the missing ABS terminal also did not blow so that may have been a previous, rob peter pay paul situation. All of the spare fuse port locations were empty... Brake lights and blinkers also are out. When lights are on in the truck and the left signal is engaged, the left light tail light turns off while right tail light stays engaged. Nothing happens on the front flasher. Same think happens for the right flasher.. Right tail light turns off and left stays on.

So far, I know I need a new AC compressor assembly because clutch didn’t engage when I jumped the clutch terminals with a fresh 12v supply and ground. But another problem is I’m not getting a 12v supply through the connector in front of the AC clutch. This is when the AC button in the cab is on and lit up. I’ve pulled the 40amp circuit breaker in the interior fuse panel and it tests good. Fan/blower is working fine just get hot air. Tomorrow I’m pulling the AC controls from the dash and testing them to make sure it is doing its job passing the voltage. Other than the circuit breaker I haven’t found any other fuse location or relay that could be faulting and not passing current through to the clutch. Also, no obvious sign of a cut or damaged wire but I haven’t traced it all the way back into the cab just yet.

Same issue in my 04 CV713. Was there a resolve to this?
