I have seen a few things cause the cruise not to work in gm trucks. First thing see if it works with the headlights off, then turn them on and see if the cruise kicks out, if it does check brake light bulbe and grounds in the tail light housing. A few other things to check, see how touchy the brake light switch is, the brake pedal maybe actuating the brakie light switch on bumps and kicking the cruise off. Check the blinkers and hazards, these have had issues with the turn signal switch. Check the ground behind the battery, I believe it is g103.

Oh ya, check all fuses first!!!

So , here is what i did : Checked fuse -ok,pulled out rear tail-light assy and checked bulbs etc-ok . Went out for a drive checked cruise ---didn't work , tried a couple times --no go. My headlites are always on [running-lites] but turned the light switch on and tried again and WALA !! cruise worked , turned light switch off and cruise still worked and I hit breaks repeatedly to disengage and pushed button again and cruise worked .I HATE fixes like this , because I didn't really do anything ?? So , is it the switch itself in the steering stalk ??

Thanks again for your help

Thats terrible that you fixed it wink , becuase that just makes it that much harder to fix grin .

Sorry, I would still check the grounds, you said you turned the headlights on and it started working, when you did this did you hit the dimmer at all? If not I dont see the connection between turning the lights on and the cruise switch. I would check grounds more. If you did actuate the dimmer switch then it is possible that the combination switch is bad.

When I turned the lites on I hit the dimmer to put them on bright before I touched the cruise button .What other grounds are you suggesting ?

Thanks Again

The ones in the rear tail light areas, and the one by the battery.

So today I took to dealer who diagnosed the problem as the 'cruise module' is failing. The part is $683.95 , and labor is $56.00 to replace . I guess I'll be using the foot for the cruise from now on , holy cr_p I didn't think the whole cruise assembly would be more than a couple hundred . So there you go .

Why not pick one up from the local junk yard? I'm not a huge fan of buying used electronic parts but the cost savings would be huge!!

Actually , I went on-line and found a new one at a GM parts house for $355.65 , I'll check for used also to see how it compares . Thanks for the tip ....
