1993 F150 Cruise Control Schematic?

[MossRoad]

Back in September, 2007 my father in law took his 1993 F150 into a Ford dealership because he got a recall notice on the cruise control. Everything was working correctly, but the recall said it could burst into flames, so he took it in. The dealership said Ford had not yet gotten the replacement parts to the dealers, so they disabled the cruise control until the parts arrived. 6 months go by and F.I.L. keeps calling. No parts. Finally last week he calls again and they tell him the parts are in. He takes it in, they install the parts, he leaves. Cruise control doesn't work. He returns and they tell him they don't repair them, they only install the parts from Ford! He tells them it worked when he brought it in and they made it not work. They refuse to repair it and offer to run $98.00 diagnostics. He leaves, mad, as would anyone else. I sicked the local newspaper on them, but they told the newspaper that it broke over the winter and again refused to take the blame.

Anyway, I want to repair it for him, so I'm looking for a schematic of how it works. Anyone have any links? It would be most appreciated.

I would start with the owner of the dealership, not the manager, or service department head. Then call a competing Ford dealership, or complain to Ford Corporate. I know the dealerships usually get hosed on the recalls, but they should take it for granted that the cruise was working properly(or should have checked it) before they disabled it, and fix the system.

Some dealerships are better than others. I had a Ford Aerostar that threw a 4WD check light and I went into the dealership to get some tech info. While I was looking at the schematics and the code values for the AWD system in a shop manual, one of the techs asked if it had had the driveshaft recall. I bought it used so didn't know. I found what my code meant, a front sensor fault, and while he checkd the VIN number, I swapped the two connectors between the front and rear sensor out in the parkinglot and turned it into a rear sensor fault to proved it was not a wiring problem. About that time the tech came back and said I had not had the recall which included a new driveshaft and re-enforced transfer case rear housing.

I had parts look up the price($179) while he scheduled the recall repair. He also knew I had a bad sensor and I told him I would take care of it after they were done with the recall work. I picked up the van a day and a half later and no 4WD check light. I looked under the vehicle and there was a new sensor installed. I asked the tech who scheduled the repair, and he smiled and said merry christmas(it was july) And I didn't even buy the vehicle from them...

I wish him luck...

That's next.

Then call a competing Ford dealership

Why? They didn't break it, so I doubt they'll repair it for free.

complain to Ford Corporate.

We did. They have no control over the dealership and will not help due to the truck being a 1993 with 184,000 miles on it. They will turn in a report of our dissatisfaction to some group that oversees the dealerships and he said it will make its way through the corporation and back to the dealer.

So, we are resigned to the fact that dad got hosed and we want to fix it ourselves. Hence, the need for a schematic.

Another dealer may take pity on you and treat it as a warranty issue on the recall, but they'd be very nice to do so.

On my truck odd things can affect the cruise control, the center brake light needing to be replaced for example. There was also apparently a second recall kit for the cruise after the first one, I'd make sure you got the second flavor. You can also try the last entry here and see if that gets things running.

Moss,
I think I have what you want. I sent you a PM.

Theres really only a couple of things i can think of that they could do to easily disable it . 1 would be to pull the cruise control fuse or another would be to disable it with the hand held programer if the truck has a computer . If the update has been done it should be an eazy matter to get a garage to plug their universal programer in and activate it again .
