Cruise Control
 

Hey guys,
My cruise quit on my '99 3500, and I checked the fuses, good, the wiring, good. The cruise light doesn't come on, nothing works. Any help? I really don't know anything about cruise, and I don't have a book for it yet. Thanks ahead of time.

the crusie button itself may have gone bad... can u wire in a new switch to see if it activates it?


i dont know much just tryin to help you brain storm

sounds like the switch is bad because if it was somethin else the light would come on i think,
find the wire that controls it going into the steering wheel and see if you can unplug it it and and put it on like a toggle switch to close the connection and see if it works then ill try to find some more info

i dont know if this will help i couldnt get the pictures to come with it

if youve done any work under your hood, check the vaccum lines first, that was the very problem on my truck, same year

Thanks for the pointers, I hope to get some time to try them this week.

i does sound like a electronic problem though, if its was a vacuum leak the light would at least come on, thats why i think it has to be in the switch

my light didnt come on, hmm???:humm:

tiz the cruise button on steering wheel :yeah:or clock spring
