Watched the videos and read the forums, No "click" on call for heat

[raddelm]

1994 Wilderness 30R using an Atwood 8531-III, I just bought it used. AC works fine, but when I switch over to heat no click in the ceiling. When I go to the safety switch on the Atwood I have 12V going in and out, when I jump 12v to the motor wire it runs fine. And if I put 12V to the blue wire on the time delay relay that's mounted to the furnace front the heater kicks on and works perfect. So does that mean I need a new time delay relay or a relay somewhere up in the ceiling. I pulled out the AC board and its a 7330A321. Do I need to replace that AC board or is there a different relay in the roof elsewhere?
