Cruise Control Problem

Probably best to post this in the tech group, you'll get more help in there

I am faced with a similar problem, but in my case, it seems to be an intermittent alternator output. Maybe you can trace your wiring with a voltmeter. Me, I'm at my wit's end, because my circuit diagrams in my *books* do not match the circuits in my vehicle! Not for troubleshooting beyond the *replace this fuse* level.

This may not be an option for you, but I just dug out my Amprobe Pasar Current Tracer, and will detach my car battery, subtituting a 9 volt pocket battery for the transmitter power source. The transmitter (fox) puts a pulsed RF signal on the line/wire of interest, and you trace it with the hound ( receiver ).

This way, instead of going through 1100 wires in 20 different harnesses, I can follow the RF signal to where it -stops- or becomes markedly attenuated, and focus my attentions there, working =back= from the alternator to the ignition switch, through wherever the RF signal takes me.

I *think* there is an inexpensive version of this device at sears. Inexpensive as in less than the sales tax I paid for this monster. Although, over the years I've certainly recovered my cost for the

Get a fox and hound circuit tracer at Sears. My Amprobe kit cost IIRC near $600 at a specialty house. You can do it for maybe...$50 ?????

Lg

GM cruise breaks wires (4 wires) at the area where they exit the stalk and begin the routing inside the steering column. This is a common problem. It also means removing the wheel to replace (most times but not always) and to reroute to replacement stalk/wiring.
