okay guys i bought my brother a 2003 accord v-6 automatic, and got put though the ringer on this one, new lower control arms, front struts front brakes, timing belt, oil pan to replaced striped drain plug, rear cat replaced, had to replace inside fuse box/multiplex to fix the door locks not working, repalced the clock spring for air bag to work, now to the problem the cruise control does not work at all press the button no light on the dash comes on i've replaced the steering wheel switches and checked the fuses , but this one has me stumped and im an ase mechanic, any ideas? also the radio when you first start the car goes though all the modes am/fm/cd back to fm and then is fine rest of the time these are my last 2 issues i need to figure out for him, any help would be appreciated

 

Do you have access to a scanner that can read the communication codes and gauge control module codes?

I'd also say that the best item to purchase is a shop manual for that accord. You can get the pdf of the shop manual from automanualsource.com for $22 and download it immediately.

The wiring diagram has a lot going on. You can start with the simple stuff like are you getting power to one of the pins on the cruise control switch?

 

Since we don't know if it ever worked before all of the work - clock spring has me worried. Assume the master comes on with no issues. Check for a good signal from the wheel set switch to the control unit as a start.
