Question about 2002 Chevrolet Tahoe
I checked all related fuses,checked switches,checked wires at servo,all checked ok.Bought new stoplight switch and new servo.Still not working.About to pull my hair out.Any help would be greatly appreciated. THANKS
Try from Servo control follow connection To I beleive Transmission casing . Look for Burnt wiring / frayed / damaged ...Cruise should maintain speed signal Like speedo cable . Computor management black box / ECM may have direct control so Look for engine bay fuse boxes = 2 under hood . More fuses ++ relays 2 check inside cover is diagram of size + what it controls . A Reset 2 ecm may help by disconnecting Battery - Let sit 30 mins.. Older models + 4 wheel drive Trans has Gear wheel of plastic 2 count revolutions as speedo cable does . If said wheel teeth have worn out then Cruise counts incorrect or fails 2 activate . If you replaced brake pedal Light activation switch then be sure brake Tail lights DO work if not the cruise will fail as brake pedal is part of safety feature to turn it off in emergency disconnect . The signal light Stalk that Turns off L / R signals is Common Item 2 wear out BUT it also controls Turning on cruise or setting ...IF you have Steering wheel on / off / setting control - then issue can be frayed / cut wires due 2 steering wheel movement ....solutions remove wheel BUT 1 st disconnect Air Bag Fuse then wheel and search connections .....Good Luck ...

after reading every post on every forum about the cruise control, I decided to pull the brake switch off of the pedal and have a look. I read somewhere that there is a spring loaded mechanism inside the switch that goes bad and makes the cruise think the brake is engaged. Upon inspecting the switch I saw a flat white bar that the brake rod depresses that engages the mechanism inside the switch. So like I always do... I sprayed the white swtch bar with wd 40 and worked it with a screw driver by pushing it and realeasing it until I heard it make a solid sounding click as it engaged and disengaged. I reinstalled the brake switch and all is well. Seems a little dust has clabbered the lubricant and was causing it to stick. So all is good and my cheap @ss didnt spend a dime. Total time including research was 1.5 hours.
Hope this helps someone else

SOURCE: heater blower switch does not
Do you have power to the switch? Do you have power to the fuses? They may not be blown but they may also not have power. Not a likely scenario but possible. First look for power to the switch. No power trace to fuses. Next check if switch is getting power doe switch send power. Does blower motor receive power after you verified that switch has power. Is the switch from the dealer or a/m? Try these things first. If the switch is used than the switch is probably bad. Also there is a resistor on the blower motor that can go bad and that could be the problem.

SOURCE: blower control switch
I had this same problem and it turned out to be a simple fix,my problem was the hot wire contact on the blower itself.Fix was cleaning the contact w/sandpaper and replacing the part on the hot wire that connects to it.

there's a button on the right side of the steering wheel that says serv push that button. It's put right there for when they use them as police cars you can cut the headlights off. You will probably notice that dash lights are on.
