Mk1 Cabriolet 93, no main lights or windscreen wipers

Hi guys ! first time to the forum, just bought a 93 mk1 cabriolet ! Reason for the help is that I have 2 issues

1. Main lights (low beam ) not working, but smaller h3 high beams working. The tiny 'side' lights on the main lights work but not the main part of the light
2. windscreen wipers are also not working
3. high beams work but they dont stay on only can push the bar forward and they come on .

I have checked with my limited skills in auto electric.
1. fuses all seem ok
2. looked at the main bulbs and changed no difference.
3. looked at the light switch on the right side of the instrument panel seems loose etc, pulled it apart and put back together nothing looks out of order.

From research ? but was wanting help
not sure how but one of the stalks not working ? the windscreen wiper one perhaps ? not sure how that would effect lights or i need to replace the light switch unit ?

Thanks all for the help !

Sounds like the load reduction relay is wonky, Does the heater fan work?

If you didn't check the fuses with a meter, sometimes they go bad and you can't see it.

Cheer Briano1234 ill go to the shops and get myself a multi meter ! and double check.

Ill check the fan and let you know ! really appreciate the message

Cheers

Hey Briano, ok so i checked no HVAC either. strangley the hvac and wipers were working (but the low beams werent) and then all of a sudden all went.

I hold my finger on the load reduction relay while turning the ignitiion and feel a click, but nothing working.   I can then assume this is the culprit ?

And ill get one ordered. I might not have the skiills to bridge things as i have read in other forums to check they work !

Again amazing help thanks again. John

Here is a explanation of the Load reduction relay "X" circuit as that is the wire path in the Schematics.

The "X" Circuit from the Ignition Switch. | VW Vortex - Volkswagen Forum

I would order an ignition switch just in case.  Read the above.

Hi,

I am patiently working towards recommissioning a similar car which has been off the road for about 10 years. I encountered LOTS of electrical issues including the ones you describe.

I ended up by simply working through all the electrical connections cleaning and/or replacing spade terminals as I went along.  

The low point was dismantling, cleaning and re-assembling the "CE1" fuse unit - including soldering up a couple of the fuse terminals so that contact was re-established with the fuse blades.

My stalk switches were also corroded. Difficult to get at but they can be cleaned up. I did invest in some electrical contact cleaner aerosol spray.

Not for the faint hearted but thankfully there is very little on these cars that can't be fixed with a voltmeter and a test lead or two.

Good Luck!

Hi guys. I am having same sort of problems. I have replaced my light/ indicator stalk to no avail. When light switch is ON the light stalk does not stay on main beam. When I try main beam the wipers start moving with lights on. Heater doesn't work full stop. Wiper stalk doesn't work. Lights on or off.

Are we talking about the plastic bit behind key barrel. When I ordered my indicator stalk they didn't have any think it was a five pin

Try the load reduction circuit.

I bought a new relay , not fixed. Took the ignition key switch and it is cracked. It's on order. Shame I didn't check when apart but it's only 30 minutes work

On earlier cabbies that is correct, on later Airbagged units it is a wee bit longer.
