I recently fit a slimline fan to my ph.1 gti6, this is connected to the OEM wiring.

I ran the car up to temperature and the fan kicked in as normal. Since then the wire to the fan broke so it stopped working, I've now soldered this together but the fan now won't work. I've checked all the fuses under the steering wheel and two were blown, I've replaced these and this has had no effect, which is odd given that everything else works on the car.

Is there a way to check if the fan wiring is ok? On later cars you can unplug the brown temp sensor and they'll come on but a ph.1 doesn't have this sensor. Is there another trick to getting the fan to come on on a ph.1?

In addition to this, does anyone have a fuse diagram? I'd like to check fuses and relays etc. but it seems coincidental that the fan wiring and relays would have stopped working and I suspect that it's something I've done so ideally I'd like to check whether or not the wiring to the fan is good. If it isn't I know I've got to re-do it again, if it is it would point towards a fuse I've missed or a relay/temp sensor.

Perhaps you can bridge two pins on one of the relays or sensors?

Thanks

Thanks for that, much appreciated.

I'll check them. Are they in the relay box behind the ABS unit? I cracked the lid but only saw relays, perhaps I just missed them in a glance.

Is there a way to force the fan to operate like there is on the later cars? Changing a fuse etc. and then warming the car all the way up to see if it worked is quite time-consuming.

Missed that detail, yes it is a non-AC ph.1 gti6, no brown temperature sensor in the thermostat housing, so single fan.

I've swapped the fan for a slimline one. The connection I made broke, I've now fixed it properly, could well have blown a fuse so I'll be sure to check the engine bay ones.

Edit: Checked engine bay fuses, none were broken. There was a cover inside the fuse box that was difficult to pop off and I left it as it seemed to cover the wiring into the fuse box.

Will do that, probably tomorrow. Thanks.

The multiplugs on the main loom are clean from what I can remember. I am convinced this is related to me fitting the new fan.

6v would be low speed, if bridging didnt start the fan then theres an earth or relay or motor at fault, but you are getting power somewhere
