Stumped with problem
-
22-01-2009 2:57am#1Driving a couple of nights ago my headlights gave up and also my wipers. Sidelights are still working and the old vw trick of flashing the full beam with the wipers switched on gets the wipers moving.
So it's like it's not getting it's ignition power to the lights and wipers but I can't find a broken wire and all fuses are present and correct. Just wondering if anybody has come across anything like this before? Am I missing something simple? Before I start stripping out the dash which I really don't want to have to do
It's a Mk2 Golf GTI0

On further investigation the rear window demister isn't working either. All of these problems happened in the same instance so I doubt it's the switch. I know that the wiper switches were dodgy on the early mk2 but my switch is from a late mk2 and the MFA which is on the switch is working fine. I'm grateful for all suggestions though
What I think myself is that it's the switch on the ignition barrell that's not sending an 'ignition' signal. I'm hoping it's something simpler though0 -

The fact that the MFA is working is not related to the operation of the wiper stalk. It's the contact on the wiper switch itself that cause the problems. These contacts are located down near the steering wheel - the MFA contacts are at the other end of the switch. In my VW parts days I sold plenty of wiper switches with MFA control.
As for the ignition switch theory. Your VW has two ignition live terminals. One is contact 15 and the is the X contact. Basically the requirements of the ignition live terminal are too much for one wire so only part of your Golf is fed directly from terminal 15. The rest is fed via a relay called the X contact relay. This is mounted on the fuse box. If you had a problem with the ignition switch then plenty of other electrical items would stop working at the same time.

The switches fall asunder when they're dodgy and by playing with them the wipers just go on and off intermittently. I can get nothing from mine now though.
I was thinking that about other things not working, my indicators and brake lights are working fine. Lets hope it's a relay so Thanks CTK 0 -

hasn't been working for a while now. Fan is seized. I've had a million other jobs to do and I've gotten through them and the fan was next. It was just blowing fuses 0 -
Are you sure the fan is siezed? The three things that you have mentioned so far all get their electricity from the same relay.........
What is the engine code on your GTI? The reason I ask is that I have a full set of genuine VW wiring diagrams for a Passat of a similar year and if your engine is installed in a Passat (good chance) then these wiring diagrams for a lot of components, wiring colours and fuse box runs will be almost identical. I can copy the relevant sections for you and give them to you on the 8th.
