There is a actuator on the right side of your leg while sitting in the drivers seat under the dash. It has a plastic rod for actuation manually actuate this diverter and should be the problem.

No, you don't have to remove the cab. Pull the radiator, A/c condenser, trans cooler and core support and pull it straight out the front.
SOURCE: Cruise control not working
The pump is located on the passenger side of the engine compartment, back by the firewall. Look in the middle of the firewall by the cowl and you'll see a small plastic line going into the cowl. follow it back and you will come to a T fitting. Follow it to the passenger side and it will go into the Vacuum pump that controls the Cruise control.If you follow it to the other side, it goes under the Battery box. this is where the Servo for the cruise is located. Check the lines for small cracks, wear spots or even breaks. The plastic line can get beaten up pretty easily.
The easy way to see if it is your vacuum pump, turn the key on and listen. you will hear 2 distinct sounds. The first sound will stop in about 15 - 20 seconds. (fuel pump?) the second sound is the vacuum pump. If it turns off in 45 seconds to a minute (or slightly longer) the vacuum pump is probably ok, as are the plastic lines. The sound of the pump stopping means that vacuum has been achieved and is holding vacuum. If it keeps running, the pump is bad or the lines have a break in them. If the lines have had a hole in them for a long time, the diaphragm in the pump will have gone south. This is not a servicable part and the pump will have to be replaced. The pump is available from a dodge dealer but most likely the parts guy will not have a clue as there is no picture in their manual and a very poor description. When talking to them ask for a "03 Ram 2500 CUMMINS Cruise vacuum pump"
The part costs $212.70

In the engine compartment, locate black vacuum hose that runs from brake booster check valve to intake manifold, there will be a small vacuum hose attached to check valve at the power brake booster check valve. This is the vacuum line going to the heater control unit,check the hose all the way to the firewall, repair any leaks you find. And that should take care of your problem.......GOOD LUCK
