Hey everyone, hope all is well. So, this little bugger locked my throttle at 70mph going down the highway. Fun times! Dealership said it's discontinued and they can't get one. I've done some googling but I really am not certain what I should buy.
1993 E150 5.8L cruise servo. Part F2TF-9C735-AA
Would any of these work? Or should I be looking at something else?
Hi Cody6051. That number F2TF-9C735-AA is not the actual part number though some sellers use it as one. That is the Ford engineering part ID number. You should call Ford back up and ask them for the actual part number. The part number I found is F7UZ-9C735-AA.
Decoding the prefix number, F stands for 1990's
7 equals the actual year, hence 1997
U stands for Econoline
Z stands for the engineering group
So 1997 Econoline. Since your van is older then 1997, that means there was an original part number and it was superseded by F7UZ-9C735-AA
I would call Ford back up and ask them for the actual part number and see if they can give you both part numbers. Ford also completely changed their part number system quite a few years back and so there may even be a 3rd updated part number... What does it matter? It gives you more options when searching for the part. Not everyone lists all of the part numbers. Some sellers list the engineering ID number thinking it is the part number. others may use the old or new updated number.
Also I saw a post some time back where one of the gears in the box had broken and the person was able to repair the problem. If yours is not working, have you taken it apart to see what might have stuck?
I found out the circuit board is the only custom thing on these servos. So I gutted out a good ford Windstar servo, put on my Econoline Circuit Board on it and works like a charm!
annaleigh. thank you very much for the write-up. F7UZ-9C735-AA is the number the dealership gave me. The reason I'm here is because my research led me to the same conclusion MoeDaMaster reached. I took the part out today, but I can't tear it open for a couple days b/c of appointments.
I guess I'm just hoping Moe is right, b/c finding these things, even with the part #'s from yoyo, is difficult.
I think MoDaMaster is on the right track. I don't know personally that every servo would interchange but the circuit board is almost certainly designed for specific applications.
MoDaMaster has a 2004 while you have a 93. The first year for a Windstar was in 94. You might look at a salvage yard and see what you can find that might match and then if you want a new one, search the part number for the vehicle you find that matches.
The more vehicles with servos that match, the better for you if you want to buy a new part to swap your circuit board into. When searching for parts for my van or helping others here at FTE, I find there is a big price difference for the same part but different application. I bought a new Motorcraft IAC valve for my 88 for $35. The part number was listed to fit an Aerostar but I found that it also interchanged with my E150.
here is a video where the guy does like MoDaMaster and uses a servo from a different vehicle.
Seems like almost once a week another of these electronic VSC servo questions come up-----they are VERY YEAR SPECIFIC and if you happen to stumble across one from another year or Ford vehicle series and it is a true plug n' play swap that's purely coincidental. It is NOT a common occurrence!
The mechanical part with motor, gears etc are pretty much the same identical parts. Where everyone goes wrong is NOT knowing or realizing the electronic control "brain" is what's different. This is because Ford purposely had these built to NOT be interchangeable. The chassis wiring plug is also the same BUT the communication wires are not in the same locations.
The video above speaks ONLY to the mechanical part and how he swapped out just that part---lucky for him the electronic control "brain" had not failed. More often than not its that portion being the problem.
OP's van is 28 years old so finding an exact part will be difficult at best. Obtaining the Ford original part number from the parts catalog is just about the only way to find and use the correct part.
Called the dealership and told them I needed the original 1993 part numbers. He told me F7UZ-9C735-AA was the original number. He said I was likely finding engineering numbers listed, as y'all said. He did give me 2 other numbers to try. F7UF-9C735-AA and F7UF-9C735-AB. I've struck out looking on the net looking for those exact numbers as well. Any other ideas?
It would be nice to find the "original" part number. If you scan down this page you will see the fitment for part number F7UZ-9C735-AA it goes from 1992 - 1997 https://www.fordpartsgiant.com/parts...-9c735-aa.html
Again the prefix for the current part number is F7, that means the part was designed, redesigned, updated or altered in some way since 1992 when the original part was manufactured. That original part number would have started with F2. It could have been a F2UZ or F2TZ or some other combination but would have started with a F2
When looking up ford part numbers it is not at all uncommon to see a part fro example, F2UZ-******-** superseded by F7UZ-*****-** If we could find that original part number, that would give another search option
Looking at your links again, I believe I might try the $29 part. Spark Surplus does have 30 day returns. I have bought a few things from them and they were new and worked fine. If it turns out to be the electronic board then I would just get another board from a junk yard...
Well.. I ordered the 30$ part. It has the same number engraved as the 80$. My circuit board looks amazingly clean under the gel. I'll use my board, and update this thread. Unfortunately, it might be a couple weeks:/
Thank you very much, annaleigh and everyone. Hopefully this works
I installed a complete NOS servo that I bought on Ebay for $35.00 on my 1993 E250. I think the servo was from a Ford Escort. The part number was F7CF-9C735-BA-D . It works flawlessly. As that video shows,the only pin that my van doesn't use is the one that lights up a "cruise on" light on the dash. I was going to change my electronics, but I gave it a try first as this servo was all new. The only thing I did was make sure that the cable pull was the same color. Not sure if that matters , but mine was tan and some are black.
^^^^ Its kinda good you checked your purchased part against the exist but I don't think the cable pull attachment has any significance. From what I've observed the servo's are physically the same (electronics configured differently) but the cable assembly running to the throttle body will vary according the the vehicle and year.
Ugh. Tried the new servo with my board. Nothing worked. Checked both fuses that had "speed control" listed and they were both good. Should I try the board it came with?
