Wipers and alarm issue HELP!

Swordjo · 17th January 2019, 16:45

Hi,

I came out to a flat battery the other day and when i got it going the alarm symbol was on the dash. Car was fine for a day or 2 and then i looked out of my window to see my alarms going off and wipers moving.

Turned the alarms off and started the the car to make sure battery wasn't dead (fired up first time). Pulled the key out and the wipers startes going again. I had to pull the wiper fuse to get them to stop.

After reading a few threads i checked plenums and the one below ecu was blocked but didn't have any standing water (it may have drained away?)

Cleaned the plenums and have just fitted a brand new 096 batter to replace the smaller one which was in. All fine for 5 mine ans then the wipers come on again.

Boot has been wet so have cleared that out ans bought new seals. I don't have satnav but there is a changer in the boot for the kenwood system. Could water at the rear affect electrics. Have also checked footwells and they are dry including near the bcu.

In short.. HELP!

Thanks,

Jonathan

I had the exact same thing happen. About 3 times through the night. Although the battery had enough in it to start the car. A new battery cured it, never done it since. I still use the battery as a back up when caravanning. Strange things happen when batteries start to go downhill.

Put a brand new battery in and it was still the same. Also did a 30 mins battery reset and now car won't lock. Just beeps/toots when pressing tbe lock fob (have tried both keys). Getting very frustrating now

If its beeping when locking, that indicates something open

Check the bonnet switch. Open the bonnet, push down on the switch, then release.

I've gave that a go too, to no avail. The doors don't actually lock now, just beep. Even the key in the lock won't lock all the doors now.

The only way i can lock all the doors is to press the button next to the handbrake.

The wiper issue seems to be resolved after the battery reset and swapping the fuse with the one for rear wiper fuse ( i have a saloon so dont have a rear wiper).

Could be a body control module issue, I had a 75 once that used to unlock itself and wind all the windows down!

Or maybe a K-Bus fault.

Thanks guys I'll look into these.

Morning update:

Wiper issue wasn't sorted, looks the the fuse i used wasn't working hence me thinking I'd solved it!

Car will now lock with the keyfob, however alarm now goes off after a few mins.. has me thinking it may be bonnet sensor or due to the wiper issues possibly is the BCU. Will need to wait to the weekend now to investigate

Have you got the highline IPK? If so, with the key to position II, and with the driver's door open, does the door open icon appear?

One other quick check - are the front window switches still operating their own windows or have they swapped sides?
