Hello all. I ended up buying the fox well scanner and found S118/1. S118/2. And S119. I need to get the appropriate part numbers for these micro switches and a vendor that sells them. Any information will be greatly appreciated. Thanks in advance
I think you might be misinterpreting what your problem is. The odds of having three bad limit switches at once is practically nil. You need to go through the troubleshooting procedure to determine what the actual problem is.
Very possible. The two side limit switches seem to be fine. The long one in the rear has a broken rod (the plastic rod). When the issue started , I had put the top up and heard a pop sound in the pass side roof area. Cycled the top again and all was fine. Next day I go to put up the top and nothing but an error on the dash saying visit work shop. I took everything out of the trunk headliner etc and checked all limit switches and cables but all I found was the rear switch broken. I believe S119
I’ve got a B1194 ID reading on the scanner. Is this a generic code or does it identify a specific area. This thing is really starting to get annoying. Why so complicated
B1194 is implausible status of S118/1, S118/2, S119. If the code is current, look at the status of each of those three switches. It is probably showing tubular frame open (S119) while the tubular frame is locked (S118/1, S118/2). Obviously it is not possible to be both at the same time.
If the rod on S119 is broken, just fix it first. Don't try to fool it or out think it, jumpering it will insure that you get a B1194 code anytime the frame is locked and you will be in the same position you are now.
Removed it from the holding pins. Inspected the plastic rod and switch and all looks good. I thought the plastic rod was broken but after removing it I noticed that it had a taper on the end. No signs of fluid leaks and wiring looks solid
You should be able to read the switch positions with your Foxwell. Start with S119 and see if it is changing state by manually moving the switch. If it does, reinstall the switch and make sure that it is working properly compared to the trunk position. If it looks okay, go to the S118/1 & 2 switches. Check their status with the frame locked and unlocked and make sure that the readings on the Foxwell correspond with the actual position. Note that S118/1 & S118/2 are in series, so if the locking status is not correct you will need to check the switches individually with a meter.
There are numerous other possibilities, but given the B1194 code, I would start with this.
So, to clarify, on the Foxwell, S118/1 - S118/2 are switching between recognized and not recognized when the frame locks and unlocks and S119 is unrecognized when the trunk is closed and recognized when the trunk is open backwards to accept the top?
Mike. I checked the pass side. No broken pin but it seems the switch was stuck. As soon as I jiggled it everything started working. Maybe that was the pop sound I heard before all of this fun began. Thanks for all of your guidance. I was seriously starting to think about Dynamite
Mike. Got the thing to work a couple of times, then got a B1 644-004. Error. I replaced the relay just because I had one and nothing. When I jumped 30 and I believe 87 the pump activated so I know it’s working. I had to top it off because I had removed the screws when I lowered and raised it manually and oil bled out so it was kind of low. I do know when I was cycling it all would work but the deck lid would stay open because the flaps wouldn’t fold in. All of the switches are identified in the position they are in .
when I go to the activation page on the fox well 440. 457. 452 . 455. 456. 453. 454. 450 451 458 are not identified and then 317 invalid intermediate position. And 318 319say no. 320 not identified 321 not identified 322 No 323 no 324 no. It has to be something really small that’s causing all these new errors. I cleared the B1 644-004 code but it stays put and won’t clear
First of all, don't be concerned with any of the parameters that are showing 'not identified' or 'not recognized'. This just means that that switch or condition is not 'made'. For example, if the roof is not at the windshield, S69/1 should be 'not recognized'. Also, 317 is probably reading 'in valid intermediate position', not 'invalid intermediate position'. This is a parameter that tells you the roof position as determined by the roof module. In can be closed, open, or in between (in a valid intermediate position).
Now to the problem at hand: Error code B1644-004 is a short to ground on the roof module to pump relay wire. Unplug the pump and unplug connector 1 from the RVC module. Check resistance of pin 10 on connector 1 to ground. WIS says > 30k ohms, but it really should be infinite. If it fails this test, there is a problem with the wire. If it passes, the problem is with the relay or module. You could also just unplug the relay (with pump and module still connected) and see if the code will clear. If it clears, you probably have a bad relay.
I will try that first. There was oil in (I assume) the module which is on the side of the pump, long skinny box. I sprayed some electrical contact cleaner in and blew it out maybe I fried it out. I will take it apart if the relay test is inconclusive
The plastic clip that holds the cable in place for the center flap is broken. For the life of me, I can’t find the correct name or where to buy one. Would anyone know where I can look
The plastic end is not available by itself, it was part of cable 230-790-00-59-64, which appears to be discontinued. I was just getting ready to have one made for my Red '03, PM me if you are interested in one. I'm assuming that it looks like this:

I will be working on the car tomorrow and will see if it looks like the picture. If so which I’m sure it does, I’ll send you a message. Thanks
