Many thanks for your informative replies. Eventually located them, both blocked, drivers side relatively easy if you have access to a ramp/lift, passenger side more cramped even with lift The passenger side came away from the car while fiddling with it and proved impossible to refit from...

If you set the climate control up as previously described,, then switch unit off with switch, wait a few moments you will hear or feel the relays switch off, then switch on you can hear or feel the relays close as they engage again, this is not instantaneous and may take a few seconds.

Yes these are the relays, the numbers I quoted came from the circuit diagram, not part numbers, as far as I know these are the only relays in this part of the car, I recently had a similar problem to you in that my blower fan would not run and I used the procedure described to identify a fault...

Yes, if I remember correctly they should just push up to come off their clips

Disco 2 td5 automatic 2002 pre facelift gs. As I understand it, the air con evaporator has 2 drain pipes that exit it on the passenger side at the front of the heater/ air con unit behind the air duct by the central console. What exactly is the path of these pipes and where do these drains...

No, 5 wire R176, 4wire R104

The short answer is no , as the transistor provides an earth path for 30 speed settings to the fan and a default speed 31 full blast is available as a back up if the transistor fails. You need the circuit diagram 2000 my rhd and the electrical library to understand the system which I think are...

I had a similar problem. The fan should run full blast as a default if your climate control unit is working. My problem was that although the positive feed at the interior fan was reading 12 volts, when the fan was switched on it tailed away to zero. My solution was to get an auto electrician...

Recently took my accident damaged disco (not my fault) to other parties insurers repair shop for inspection prior to repair where inspector said they could pull out dent using described procedure. Just wondered how feasible this was given that I thought but was not sure wings are alloy. Thanks...

What are disco2 outer front wings made from and is it possible for repair shops to weld pins to them to pull out dents. Thanks for your replies

If you have a nanocom one test you could carry out, but only when the fault is present. Look at my previous thread Disco2 xyz switch information needed where you will find a table of wxyz feeds for gear position, read the whole thread as you will see that the table is correct when read at BCU...

If you look at my recent post xyz switch information needed you will see that sierrafery has kindly posted the table of xyz switch feeds for the various gear selector positions from rave. He is correct that the nanocom gives different reading, correct as listed, when read at vaelo BCU but you...

Many thanks for your reply . Intrigued so looked with my nanocom and found that the readings matched those on the BCU and matched those on the EAT ecu if you reversed the order of switch contacts.

I would be very grateful if someone can post on here the table from rave which gives the relative states of the wxyz feeds when selecting P,R,N, D,3,2,1. Many thanks in advance

No idea but I received one recently with interesting info. Send me an email to r.simpson908@bt internet.com and I will get back to you soonest.

The circuit for the power feed to the xyz switch wxyz outputs is as follows Body control unit BCU located behind the front passenger glove box. BCU connector CO663 pin10 (brown/purple wire) CO668 pin3 to CO681 pin3 (brown/purple wire) CO675 pin 8 (brown/purple wire) XYZ Switch pin 8 With the...

If you want to read my tale of woe look back a few posts in this forum as someone has resurrected my original post about my problem.

I had a problem like you and eventually traced it to a fault in the bcu which intermittently was failing to supply power to the wxyz circuits in the switch. To check this, With the ignition at position 2, test for 12 volts at pin 8 in CO675 , this is the connection of the xyz switch to the...

Yes I eventually diagnosed the fault and an auto electrician wired in a fix. My problem was that the power feed from the bcu to the wxyz circuits in the switch was failing intermittently caused by a failure in the bcu and was difficult to diagnose as it can only be checked when the fault is...

Thanks for your replies, waiting to. Hear from other parties insurers, just wanted to be prepared as local repair shop said that they would expect repair to cost about £1500. I have not involved my insurers as other party 100% to blame and I am aware that if involved, my insurers wrote the car...
