Anything electrical sure to fail... The power window switch on the door does not work;the passenger side window door switch works fine. The dash reads " DOOR OPEN" with small red light above it.

I removed all fuses , reset battery....nothing. The door is not open. Have no idea how this happened but upon entering car to go, no power windows. Also, the door locks do not close as they did with thw car door closed automatically.

Is there a way to get the window hand cranked up? What is the fix?

BTW, the entire owners manual or vehicle care manual does not address any fuses for the front windows nor does it indicate why "door opened" may be tied to problem'

 

Do you have a voltmeter to read the voltage on your battery with the ignition off?

 

yes, I do. READ it as 12.74

 

The door close and windows must be interelated. I have had no issues with the electrics .

Is there a switch on the door latch that regulates the window power somehow? What fuse is responsible for this circuit?

 

Fuse F15 - 25A in the Driver's Side Fuse Box feeds both the locking and the window lift elements of the Driver's Door Control Module.

 

I pulled that fuse again this AM. The same message reads /red light ... door open. The fuse does not seem to do anything either in or out.

Should pulling the fuse reset something or distinguish the warning light?

This is very frustrating....having a car built without the means of shutting a window; just poor design. The alarm now goes off when i try to enter the car because the remote will not work to lock, etc. Seems all are connected somehow and very poorly designed. I have never had problems like this with my other cars.

Anyone have the solution to this?

 

Sorry if this seems trivial, but you said you 'pulled' the fuse. Did you check the fuse for continuity?

 

If the fuse is good as Whitexkr suggests, I would then be looking at the driver ajar switch to make sure it is working correctly. You should be able to test this from the connector on the driver door module going to the door, wires BK and GW.

 

The fuse was good.

Where is the door module located?

 

The module is located in the driver door/door casing. Top forward corner and comes out of the speaker recess. You first have to remove the door card and according to the instructions, disconnect the battery once the door is open.

 

One you take the door trim off, there are three small bolts in a triangular pattern in the upper right of the door that must be removed, along with the speaker, Then the module can be slid out of the speaker opening. It certainly sounds like you may have a problematic driver door module.

 

The relays which operate the window are inside the module and not readily accessible. In a crunch, you can unplug the module's two connectors. Then, with the module discinneted, take the blue connector and locate pin 7 (Orange) and 15 (orange-yellow). Numbers are embossed on the connector. Apply 12 volts between these two pins to operate the motor manually. One polarity will raise the window, the other will lower it.

 

I am thinking I should locate a used module . E-bay has some listed. Are the xj models the same as the xk model? Do you think it is wise to purchase and then try?

So if the door module goes, the windows stop working and the remote cannot lock/unlock the doors? Why are they tied together?

My older Alfa has a hand crank....windows or top does not work; crank them up!! VERY SMART!!

 

Is there a way to test the module before buying or even if bought, how do I test before installation? Seems like much work without the ability to know if this is the problem.

Any suggestions where to buy????

 

It is common in most modern cars to have combined functions controlled by one electronic module.

You need a shop with the Jaguar WDS/IDS dealer tool to access the module via the OBDII port in order to test it.

If you buy a used one, be sure to match the part number and the VCATs code, which is the software version. The VCATs code is usually on label on the rim of the spare tire well in the boot. It is the three digits after the '/' following the part number. You may need to lift some carpet in the boot to see it.

 

WOW!!!! This forum is unreal! I certainly thank you for the detailed info. If Jag had employed a few of you maybe we would not have all these problems.

Do you think that I should buy from a Jag dealer? Have Jag dealer test only?

Where other than a Jag dealer is suggested to purchase?

 

I drove the car today and parked outside in parking lot for about 2 hours. I get back in the car , the horn starts blowing, the key in the ignition does not turn it off. I put the key in the door lock and locked it manually. The horn stops blaring, the windows , door locks all work as normal!!!
No more problems! everything works perfect!

What in the world could have caused the problem? What do I do next?

I cannot trust a car that acts this way. Maybe just replace the door module ?

 

The door and security modules do not always reset properly after a battery disconnect....sometimes it takes several attempts. The system was really designed to be reset with dealer computer equipment, not the home mechanic.

The electronics in this car is one of the very first automotive designs to use fully networked computers for nearly every function. The design, though mostly reliable, is subject to some glitches. It may be that the internal fault detection 'watchdog' finally detected the problem and righted itself.

My recommendation is to give the car some time. It is possible the problem may never repeat.

BTW, this problem is not unique to Jaguar. The body electronics in my 2002 Mercedes is even more tempermental.

 

So this is something you accept as a Jag owner? This is the second time the windows stopped , but then cleared up. Do you think it is activated by heat or rain or something? I though it was from opening and closing the door.

Very hard to understand why this is occuring and if there is a fix for it. Some friends have Nissans and Hondas....over 150,000 miles no such problems.

Has to be answer and way to correct this design flaw.

Be interesting to see if others on this forum have had similiar problems and if anything has been done by Jag to address these problems. A poll should be started with the intent of measuring problem and with the purpose of interfacing with Jaguar. What do you all think?

 

If your problem is recurring, it is likely not a design flaw, but a fault somewhere.

My previous comment was assuming it was a random one-time occurance, and also regarding occasional difficulites achieving a proper reset without dealer equipment. My other point is that computer based systems are subject to occasional random faults. As technology has improved over the years, this has become rarer, but is still possible even with the best of designs.

You have a 15 year old car...you should expect some problems. The electronics in this car are particularly sensitive to having proper battery voltage. From your voltage readings, your battery seems fine, but it is possible you have corrsion on a battery connection, a ground connection to the chassis or another connection in the door. You could also have an interniitent problem in your door module.

Troubleshooting intermittent problems is difficult under the best of conditions. Without diagnostic tools, there is likely going to be some trial and error involved.
