Hi all, I have started to have a couple of electrical problems arise on my beloved Golf:
1. My driver side electric window is playing up. It will lower but then hardly raise or I have to assist with my hand. The other side works fine.
2. My battery has started draining. I've popped the bonnet and can't find any loose wires. The only electrical work I've had done recently is new fog lights fitted a couple of weeks ago and I had new head unit and amp fitted about 6 weeks ago.
Anyone got any ideas as it's starting to do my head in. I'm not much into electricary and to be honest haven't a clue of what I should be looking for.
More than likely the window problem is going to be motor/wire/regulator related.
After many many years of abuse, metal filings from the cable become mixed with the gunk in the motor guide and foul it up. Hence the slow upward movement (gravity assists it going down)
Remove the regulator mech from the door and check that the cable is in one piece. Then open up the face plate on the motor. You will see the spool that the cable is wound around. You can remove this, unwind the cable (remove if necessary) and give it a good clean. Have a look at the gears/worm drive to see that they have not worn.
Lube and replace, and it should work as normal.
With the battery. Whip out the voltage regulator from the Alternator. Check that the two brushes are not excessively worn. If so, replace. About £15 from GSF etc...
As per normal, check all your earth straps are connected and clean, and and the battery terminals and cables from it are clean.
