I saw another post on the forum about the door-open/closed micro-switch. I found an almost exact replacement switch and replaced the switch in both the driver side and passenger side doors. The attached Word document contains a few pictures of my approach. The attached pdf is the data sheet for the switch.

As a formum member pointed out there is a typo in my document. I corrected the error in the attached version 2 of the document

 

Timely, I almost order the $26 switch yesterday. I'm kind of a dolt on electronic stuff - does it matter which normally closed wire you use? Did you just trim off the other one? Any advice on making the connections?

Thanks!

 

Thank you for doing the research. I don't need it now but I know the day will come. It's always great when someone has gone down the repair path first. Thanks again. PS When Rev Sam said you had to but the entire latch assemble for a bizzilon $ becacause JAg won't sell the switch..I thought well here we go agian..major expense.

 

Good addition DrD, added your thread to the XK8-XKR FAQ thread, your first I believe. Congrats!

 

Good find! Your explanation about how you almost chopped off your hand was like deja vu. I was able to pull my hand out of the way in the nick of time, so I didn't get cut. It was definitely scary, though. I'm glad you were able to find a reasonably priced switch. I just looked and mouser.com sells them for $4.29 each. I'm not sure about the shipping cost, though.

 

One of the leads (blue) is normally open. He just miss-typed it in his instructions. Lock at the picture description.

 

Thank you for this very informative and time saving post (not to mention money saving!!)
My passenger side has just started playing up so I will be performing this fix very soon.

I wonder why this little sealed switch fails? Any way around replacement, say a clean and lube of the affected area?

 

Several members (myself included) have found cleaning will often get the switch working again but it's on borrowed time and most report complete failure after a while. Mine failed completely in less than two months.

Thank you DrDSP!

Just replaced the micro switch on passenger side with the help of your post, so glad that you found the switch and posted about it.

I ordered a D2SW-3L2MS by mistake; identical to the one you used but with roller actuation over simulated roller. The switch works great and did not need any adjustment to the lever.

Got my switch from Mouser Electronics - Electronic Components Distributor for around $14 Canadian shipped.


Thanks again!

 

That was a great description coupled with photos regarding the micro switch swap out. My windows seem fine, it's the locks that cycle back an forth when depressing the red lock key fob button while the passenger door locks up some times and other times it doesn't and when it doesn't (drivers side door lock always locks up fine with key fob) I have to depress the white unlock button on the key fob for preventing the car horn alarm sounding. Possibly I just need to replace a door locking module instead of a micro switch? Where would that module be located at and what part number is it?

Cheers,

The DDM is in the door. Here's the relevant extract from JTIS:

JTIS - Driver Door Module.pdf

P/N is VIN dependent:

To A21852: LJA2120AJ
From A51853: LJE2120AB00D

Throwing parts at a Jaguar can be a very costly approach to troubleshooting.

The door module diagram you sent me is spot on, thanks. If I access the door module and disconnect and reconnect the connectors thinking that it may be a intermittent connectivity problem and reassemble and test would I first be forced to reprogram the door modules for each door too make them operational? Don't want that to happen.

Thank you Good Doctor,,, if you're still out there somewhere...

Some things to remember when repairing and putting it all back.
1) Cut the pins with a stanley knife and remove the old switch and NOTE which way round the relay was facing when you remove it, otherwise you get into problems with it not working properly.
2) The latch to the outdoor handle can be pulled off the nipple by leaving it on until you undo the latch, then just swivelling the latch, it will just come off without breaking.
3) The Red lead and black lead are only needed, if this doesn't work then it could be that the lever is facing the wrong way round.
4) Finally just plug into car and check by putting it on the door post, before putting in the car. It could be that the lever isn't bent enough upward, so check before going to the pain of putting it all back.
5) You can use all sorts of mechanisms to secure the microswitch. I used little self tapping screws, but a small nail pushed through from the metal side would work because the head of the nail will be held in place as it's screwed on the door.

Just my observations.

 

GREAT! Thank you, Mike...
I will be doing this job,,,, AGAIN, soon.
​soon.Good and needed refresher...
