clock-spring
My cruise has not worked since I bought the truck 2 years ago. Last week I decided to investigate. I thought I might have had some broken wires because I have a tilt wheel. Sure enough I pulled off the steering wheel and the "pretty" cover around the collum and I saw a little white wire that had been sheered. I thought I was going to get by just soldering the wire back together. But I knew my horn did not work either so I looked deeper. I put my continuity tester on the leads going into and out of the clock-spring (black donut thingy behind steering wheel) I could not get continuity ( a continuous wire) through any of the leads ( wire connections) to the other side. I opened up the clock-spring with a screwdriver and the ribbon of wire that goes around in a circle about 30 times was in about 20 pieces. The clock-springs are not rebuildable and mine was junk so I forked out $150 to the dealer because none of the aftermarket parts stores in my area can get them ( I was too lazy to find a good one that might be almost out of life at the junkyard). Cruise and my horn work now and I like it!
Do yourself a favor, before you fork all that cash out. Find someone who owns a multi-meter with a continuity setting ( measured in ohms sometimes called an ohm-meter) or continuity tester, all electricians should own a multi-meter with a continuity setting. If you hold the leads of the meter together you should get 0 ohms or the meter should beep. Test yours or one at the bone yard first.
