I can relate doing the door transplant. Trying to get my hands into the small holes in the door and then maneuver around things in the door left little room.
Note: Make sure you disconnect the battery. If you trip the switch that controls the global function the window can come down even with the key off.
Best of luck.

 

Bob,

Thanks for the warning on disconnecting the battery. None of us need to lose any fingers while working on these various door components....

 

Not trying to bump this thread but found it as I research a problem with my 98 VDP that I wonder if it is related (assuming the door locks are common between the XK and XJ's)

In my case, the door will not unlock using the key. All other functions work OK (key can lock the door OK, opens by inside and outside handles, fob locks and unlocks).

I haven't pulled the panel off yet to investigate, but the only symptom associated with the key not working is that there is no resistance when turning it to the right (unlock direction). Without knowing how the lock mechanism works, I'm not sure if I have an issue in the lock itself or if there is a microswitch in the mechanism that could have gone faulty in the unlock direction.

Appreciate thoughts on whether this is related or if I have another problem and need to open up a new thread / pull the panel to see if I can see anything that has gone adrift.

 

I am no expert and can only speculate, but your issue sounds to me like a mechanical component associated with using the key in the door lock has failed. Perhaps others with far more experience will chime in. Keep us posted on what you learn as it seems these door operation issues are becoming more prevalent as our vehicles age....

 

Not the same door latch on X308 but a similar design and method of operation:



First step in troubleshooting has to be to remove the door card and see exactly what is happening with the key and operating links.

Continue in this thread with common issues regarding microswitches but if it gets X308 specific (e.g. door card removal) please start a new thread in X308 forum.

Update:

My new Omron D2SW-3L3MS microswitch arrived this afternoon. Judging by some of the photos that various members have posted of their microswitches, it looks correct. No true way to know until Wayne and I get inside the door, remove the factory microswitch, and compare them side by side. We hope to wait for cooler weather to tackle this job. Stay tuned....

 

I got all my parts in and installed the lock actuator to my existing latch assy. It works perfectly.

These are the three microswitches that I have left over. The blue bodied switch is the switch located inside my original lock actuator. The other two were mounted externally on the body of the latch assy. that I bought on eBay. They are for another model Jaguar so I am not certain they apply to our door latches. The bottom switch with the green wire appears to be similar to the Omron D2SW-3L3MS .

 

Jon, that looks like the typical micro switch, so we need to get a better understanding where it's located. Can't be much to replace, just the arm adjustment might be the only thing as it does look plug and play.
Wonder if the wires need to be soldiered into the plug wires or if we can get the old ones out and have the correct ends to insert these?
I'll do some more siphering (me and Jeff-throe),

 

Wayne,

I am guessing that the wires will have to be soldered. Looking at my new Omron microswitch, I am not sure if it can be taken apart without breaking it. We will figure it out one way or the other when the time comes....

 

You can try, it is normally pressed together on plastic pins. I would not use a tool, but maybe a finger nail. If you manage to open it (it just pulls apart), pay attention to the little parts inside. There is a blade for the clicking action that needs to remain at the right spot. I agree that if you manage to open the body, there is an off chance you might be able to swap the "legs" from the old body to the new one and avoid soldering. These legs are just pushed into a channel in the plastic body, nothing complicated. The other idea is to open the old body and if the blade is broken, somehow swap it with the one from the new switch. FWIW, even if all of that is possible, it is probably best to just swap the entire switch. On a scale of 1 to 10, the required soldering skills are maybe a 2.

Best of luck, keep us posted.

 

I agree on that, no problem with the soldier gun, been doing a complete harness for my Spit6, adding a 10 spade fuse box instead of the 3 old glass ones.
If Jon and I can get a day or so under 80 degrees we will be in heaven. Looks like more trouble getting the card off than getting the switch out.

 

The good news is that Jan's XK8's door latch assembly has been behaving properly for the last several days. Now that I have typed that, do not be surprised if the door decides to trap her inside again tomorrow....

The longer we can postpone this job, the better chances we have for at least tolerable weather here in North Carolina....

 

Update:

This door latch problem has not reared its ugly head again since the alternator was refurbished, a free Bosch AGM vented battery from Pep Boys was installed to replace the suspect Bosch wet-cell vented battery I purchased from them in April 2017, and the door latch assembly was lubricated with several shots of silicone spray. Perhaps one or more of these tasks fixed the issue. If my wife eventually reports that the door latch problem has returned, I have the new door latch microswitch ready to install (but Wayne and I will still wait for cooler weather to do the job). Time will tell....

 

That's good Jon, we sure don't need to be working on cars the next few days. Be more like lumber jacks.
Stay Safe, Miss Florence is no lady.

Yep, my Subaru is ready to roll in case we need to go anywhere during the storm. Rainfall predictions here have dropped to 5 to 6 inches and wind gust predictions have dropped to 30 to 40 mph. If that is indeed what we wind up getting, I will consider us to be very fortunate. Stay safe....

 

As a side not on disconnecting the battery. As a tech anyhting you can do to speed the process makes you money. So in that spirit dont disc battery just unplug the door latch inside the door. You have to do it anyway to remove and you wont have to unload the trunk or reset everything when done.

 

Brutal,

Regarding disconnecting the battery for this job, those who have done work inside the doors near the window mechanism always advise disconnecting the battery due to the window regulator possibly engaging by accident and slicing off your fingers. So we will certainly play it safe and disconnect the battery. That is, if we wind up having to actually do this job. I may get lucky and not have to do it....

 

Update:

This afternoon my wife reported that her passenger door interior handle exhibited the same miscue as her drivers door interior handle was doing a month or so ago. It refused to open for several interior handle pulls and then finally opened normally on perhaps the fourth or fifth pull....

What are the chances that a faulty drivers door latch assembly microswitch could now be causing the same problem on the passenger door latch assembly?

What are the chances that the passenger door latch assembly microswitch is now beginning to get flaky just as the drivers door latch assembly microswitch was a month or so ago?

What are the chances that this problem is caused by something other than flaky door latch assembly microswitches?

 

Another fine mess you got us into. LOL
You got to love these cars, they may be out thinking us.

 

Good point, Wayne. I wonder if it is the microswitches, the door modules, or entirely something else causing these flaky intermittent door handle issues. Sure hope we can figure it out before we go to the trouble of installing the new drivers door latch assembly microswitch that I have waiting on my garage shelf....

Just as I did with the drivers door latch assembly a couple of weeks ago, I will spray the passenger door latch assembly with a couple shots of silicone lubricant and see if the issue returns....
