Well, installed a new CCU and all i'm getting is a two tone warning alarm from the new ccu and the remote fob won't work no matter what I do. Car still starts and runs fine but none of the other problems seem to have been solved. Not sure what to do next!

Well, £90 worse off now following a few hours of an auto electricians time. He has checked out all of the systems to the rear, reversing lights, wiper, wiper, washer, door locks, window raise and lower stuff etc and can power them all independently so no earth or supply problems locally to each...

Hi Chaser I have checked the wiring and replaced the relays but the wiper is still not operating although there is power to the motor. I can make the wiper operate by applying a voltage to the terminals and have stopped it in the parked position but this does not seem to make a difference. There...

Well, replaced the relay but to no avail, time to call in the experts me thinks otherwise I'm gonna replace bits that don't need it. Wonder if it will pay to get someone to put a fault code reader on it or not?

Hi Optimus, I have tried to calibrate the window but when I reconnect the battery nothing happens to the rear window. I can drive it down with the console switch at the rate of an inch at a time repeatedly pressing the switch and the same back up, I get the 4 beeps after every press though. I...

Checked the voltage at hthe reversing light switch and have voltage there. even if i bypass the switch there are no reversing lights or voltage at the lamps.

Thanks, checked it out and its working, must be something else stopping the wiper and washer working and stopping the rear window moving more than an inch up or down with each press of the console button. Could it be the rear wiper relay stopping the ccu registering the wiper as parked?

Hi Can anyone tell me what connections I should apply power to to test the rear wiper motor? I have the motor out, it seems that there is power to the wiring block at the motor but no go with the wiper itself. I am assuming that it is affecting the operation of the rear window as the wiper is...

Well, replaced the rear window mechanism without any problems although the window only goes down or up a little way before you get the 4 beeps from the ccu. The rear wiper and washer switches fail to operate anything and there is no voltage at the reversing lamps. The rear window heater switch...

Pulled the rear door trim off and it appears that there is a broken cable to the window regulator, this is no doubt the problem with the wiper and window movement!!!. As regards the reversing lights, I have only tried for voltage at the lamp holder and seem to have none. The HDC light stays on...

Everything seems to work normally except the rear wash wipe, window and reversing lights, I have tested the reversing light switch and there is power to the switch and the switch is showing resistance when in reverse gear. Checked all of the fuses and they are ok. Relays for the rear window seem...

Having had the HDC, brake light TC problems, I have replaced the brake light switch and the reversing light switch on my 2001 TD4. Now I have no reversing lights, the back wiper will not operate and the rear window will not move under any circumstances including the removal of the battery for...

Thanks I'll have a look at that as well, rear window now won't move under any circumstances with console button, by disconnecting the battery and reconnecting, remote control or sledgehammer! 4 bleeps seem to indicate that the request is getting to the ECU but alas no movement. Maybe time for...

Well Now it seems that the rear window wiper will not sweep when your front ones are on and you select reverse!! As I have renewed the reversing light switch it seems that there may be something else in the circuit not right. The wiring as far as can be seen seems ok. Could the wiring to the...

Yes, checked all those, I'll delve into the wiring tomorrow. Failing that, I have dynamite!!!

Well, changed the reverse light switch. Now the HDC works in first but not in reverse and no reversing lights! Bugger. And the fuse has just blown again, looks like the circuit must be faulty, god knows where the spaghetti goes under there.

Thanks for that, i wasn't sure if the reverse lights were part of the same circuit for fuse 2 and the HDC TC lights

I seem to have the same problem on my 2001 td4 but even though I have replaced the brake light switch, everytime I reverse, fuse 2 blows and the lights come back on! I have the 2 switches down below as well but no cruise control. Not sure what to try next, ideas anyone? by the way, the switch...

Thanks for the help, I haven't located the 3 pin connectors in the picture, may have dropped down a bit, looks like a bit of feeling around is needed.

Reckon its a new changer then! Thanks for the tips though
