While waiting for the dealer to get the parts to do the cruise control recall (he had stated that the chances of my cruise control working after the fix were slim to none - it was not working at the time) I had occasion to replace the master cylinder.
I am assuming the switch mentioned in the recall is on the bottom of the cylinder towards the front. I say that because I noticed that the wires coming out of the switch, were lying against some support bracket for something or other. The insulation around the wire was obviously from bumping the metal and I could see wire. Now, I'm thinking him...switches and wires and shorts are not good under the hood so - while I was in there, I cut the wire, stripped the insulation and re-connected them with the electricians twist, wrapping all with tape and rerouting the wire so it did not rub against anything.
My cruise control now works. This is a quick check and from looking at the harness and I can see that all E-150's might have this problem.
It also makes me wonder if 12V goes through that switch and what potential for a fire it might have had.
