cruise control relay??
Just bought a 95 Ford F-350 powerstroke, and everything works except the cruise control. All the fuses in the cab, and under the hood are good. The owner's manual does not show a relay for the c/c. The question is: There are two relays off to the side of the fuse box in the engine compartment, that are not listed in the book. Is one of these the c/c relay? If not, does anyone know where to find it, or any other ideas as to why the cruise control doesn't work? Thanks..

The switch on the end of the master cylinder is probably bad. Pull the plug and check across the pins on the switch, should be continuity, if not replace it. BTW: these switches are the subject of a recall, they can cause a fire. I'd replace it anyway.
I'll check the book for the relays and post it.

Well, I tested the switch on the end of the master cylinder, and had power coming out of both wires. So I took it to my buddy's shop, and had them hook up a scanner to it, and it didn't bring up any codes at all except for no back pressure on the exhaust(which is because I put a 3" downpipe, and a 4" straight pipe on it. Any other suggestions?? Thanks..

Check your third brake light wiring and bulbs. Cruise will not work with a blown third brake light or bad connection in the third brake light sockets. Also check you regular brake lights.

Unplug the connector @ the (BPS), end of the master cylinder. Check the switch not the connector for continuity. You should get continity with the brake pedal depressed. It has no continuity while at rest. There are no codes set for this switch.
