Where in the heck is it????

'99 dodge ram 2500 v10. Am trying to find the fuse for the cruise control. I have looked in the obvious places but maybe its labeled something other than the obvious. The cruise control does nothing other than the light coming on the dash when the button is pressed. Any help appreciated. Thanks!

If the dash light is lit, then the circuit/fuse is not blown, it could be the switch itself, a vacuum connection from the cruise servo, or worse case the clockspring on the steering column

Always check the brake light switch. It disengages the cruise control when you step on the brakes. If its bad your cruise control will never engage or just click off unexpectedly when driving with it engaged.

I had a few problems with things on my '99 Ram (bought used). Everything is vacuum controlled so a break in any line will cause issues. The cruise is vacuum actuated so check the line to the canister to make sure it has vacuum.

I can check the above suggestions but I'm still dying to know where mopar hid/disguised the fuse for the cruise control. I don't have the FSM. Just a Haynes Manual and it tells you pretty much nothing. Can anyone tell me where the fuse is???

IIRC there is no fuse after 96 models, power to the cruise is off the PCM

FWIW you can download the complete FSM free off the net.

i dont know but i need a crank sensor for same vehicle any help from u or others i sure could use

One of them might do it.

As was stated there is no dedicated fuse for the cruise control on your truck. The PCM controls it which works solenoids in the servo. The servo must have good vacum to it also. The PCM moniters the switches as when to turn on and off the right solenoid in the servo. The brake switch has a seperate set of contacts for the cruise also and some models even use a relay for power to the servo. First make sure you have good vacum to the servo as I remember some trucks mounted the servo under the battery tray and could get battery acid on the vacum hose as I had some do that and cause a vacum leak to the servo. If it has good vacum you can easily diagnose the switches and servo with a scann tool. Ron

Is this truck "new" to you? If so, are you setting the cruise correctly? 1) turn it on 2) hit "set". Now the accel and decel switches work. If you don't hit "set", nothing works.

Could you provide me a link to get the FSM free. Everytime I think I have found a free site, it wants CC info.

As far as turning on the cruise control, I guess I'm doing it correctly. I hit the cc button, I see the CRUISE light up on the dash. I am traveling approx 65 mph and then hit the set button. Nothing. Nothing will catch and the truck starts to slow down.

Might help?

You have to do it in this order:
Hit "cruise" - light turns on
Hit "set" - nothing happens but it allows the use of the other switches
Hit "resume/accel" - vehicle will achieve last set speed - may be faster BUT could also be slower !!

When you hit your desired speed with either the "resume/accel" or "coast" switches you have to hit "set" to maintain that speed. If you hold the "resume/accel" switch to speed up to pass, it will resume the set speed once its released.

I thought I had the '99 FSM but its actually a 2001 (same generation). I guess I couldn't find the '99 when I needed it.

Here's the '01. Download it now before it disappears

When I click on it, it says: Link not found. Thanks anyway. I'll try downloading the FSM for the '01.

Sorry, I took it down this morning, thought you'd already gotten it.

No. From the 1999 Dodge Ram owners manual. This is the same way every modern Dodge that I have owned has worked.

To activate - Push the ON/OFF button to the ON position. In the instrument cluster, the word "CRUISE" illuminates when the system is on.
To Set At A Desired Speed - When the vehicle has reached the desired speed, press and release the SET button. Release the accelerator and the vehicle will operate at the selected speed.
To Deactivate - A soft tap on the brake pedal, normal braking, clutch pressure while slowing the vehicle, or pressing the CANCEL button will deactivate speed control without erasing the memory. Pushing the ON/OFF button to the OFF position or turning off the ignition erases the memory.
To Resume Speed - To resume a previously set speed, push and release the RESUME button. Resume can be used at any speed above(refer to the table below for the speed for your specific engine).

This is exactly what I do to operate the cruise. But it does nothing. So I've got troubleshooting to do. The cruise vacuum lines look buried in this motor. Asking folks who have already been down this path, can the cruise vacuum lines be easily accessed without a court order?
