Own a 2002 SD 350, 7.3L and have an electrical snafu that even the dealers service department can not figure out. I put the key into the ignition turn it on wait for glow plug light to go out. Truck starts normal BUT....when i go to put windows up or down nothing happens, clock and radio does not work. Everything else is AOK. Wait a couple of seconds to a minute, the clock comes on, the windows and radio works. Local service department now has three of these and mine is #4. Any ideas????

I wouldn't say dirt cheap, but yes you could change them all at once fairly inexpensively, but I would go with just the one that controls the devices that are malfunctioning.

$9 a piece is what I just paid, there are about 5 or 6, for $45.
That is cheaper than a gasser oil change.
Apply the cockroach theory:
Cockroach theory is the idea that one item of bad news is an indication that there is more bad news to come: in the same way that seeing one cockroach is an indication that there are more lurking out of site.
That is why many critical parts (brakes, tires, etc.) are replaced in pairs.

Parts that wear evenly, yes. The relays do not necessarily wear evenly.

Yup, and it is technically possible to substitute worn relays from one circuit to another.

Just talked to the Ford Service Manager and they said it was a "Battery Saver Relay in the instrument cluster." The fix was to replace the entire cluster at a cost of $700, OUCH!
