Hey guys!

Been a while since I posted but got a new surprise with my '99 XJR...

After experiencing some very heavy rains for days straight here in 'Sunny FL'
I noticed my power locks have stopped working with the key and when I open the drivers side door on the interior along with the clock on the dash. Any suggestions as to what may have caused this and proper replacement?

Thanks in advance!

 

I know what your saying about the rain (I'm on the east side of town off the 417), dang tropical storms, its keeping me from pulling out my Vette and replacing the manifold.
Check your module in the door, you need to disconnect it for a couple minutes and reconnect. Some folks may also say to disconnect the battery and let it bleed off. Its obviously easier to do the battery, but I prefer to remove it at the source. If the battery doesn't work, then go to the module.
I'm not sure about the clock issue, could be a connection behind the dash.

 

Sounds like you need to Hard Reset your car. Disconnect your battery cables while your ignition is on to accesories for a half hour or so. My driver's side window just stopped working, hard reset and now my window works.

 

According to Jaguar, to do a hard reset, disconnect the neg. batt. cable and touch it to the positive post for a few seconds. You definitely should not disconnect it while the ignition is anywhere but off.

They also say you should disconnect the battery before proceeding with any work on modules or other electrical components.

 

Thanks for the replies guys...Yup hard reset is my go-to fix but with no prevail, its still doing it. As reliable as shes been running, I've had some weird electrical woes with this one. Including the drivers side window not rolling down, and sunroof not opening (will work for a couple days after hard reset then back to nothing) and now this with similar results.

I'm wondering if my BCM is the root of the (overall) problem? Could that be a possibility?

 

So lets back up a bit....what condition is your battery in? If your not holding voltage or you have corrosion on your terminals, you'll get these ghosts. Same goes if your alternator isn't working up to par.

 

hmm...good call. My battery might be needing replaced, I havent changed it since I got the car and I've had it for about 3 years now. I'll look into the alternator also. Any recommendations for a battery for a 99 XJR?

 

Battery is your choice, I got mine from Sears by the Colonial Mall about 6 yrs ago.

 

I got it checked not too long ago and everything read properly, I'll get it checked again, thanks for the replies!
