Well got on the interstate this mornin on the way to school and turned my cruise control on and hit set but it never came on i tried it a couple more times but it never worked. Just wondering what i need to check first? Thanks guys.

 

Was your abs or brake light on?

 

How warm was it this morning. (Mine doesnt Always work if its under 40 degrees)

 

No neither the abs or the brake light was on. It was plobly about 70 degrees this mornin

 

Does the light come on indicating cruise has power? (not sure how that all works on the newer trucks....) If it is getting power, check the vacuum line from the cruise module, to the intake. If that looks ok, check the cruise module itself. (under the battery) They tend to get battery acid dripped on 'em, and stop working...

 

check for a broken vacuum line running under the battery tray up to the throttle body.

Cruise control is vacuum actuated. A leak in the vacuum line will keep it from engaging.

 

^ dry rotted/cracked vac hose under the battery tray was the problem on our jeep. i changed it last weekend and it fixed it.

also check fuse, brake light switch and clutch switch.

vwanddodge had to replace his steering wheel buttons. (i think)

 

Yea the vaccume on my ram is broke and brittle in alot of the line so i am going to replace that line. Is there any change if my ABS light is on only some of the time? How do i fix that?

 

any body got any pics on wut to look for as line location and where it goes mine has power to the unit light comes on has never engaged..

 

follow the hard plastic vac line from the front of the TB across the top of the engine to the battery area. it'll likely have a soft rubber line for the last 6-12 inches. the soft rubber is 99% more likely to crack than the hard plastic.
