Fuel pump running constantly, blower and wipers not working!!

Post

Back to the top
Hi, i've recently become the owner of the 1985 Golf Gti Mk1 convertible!!
But it has come with a few issues…

The fuel pump is running constantly, blower and wipers not working, I bought the car like this thinking the relays probably need changing.

The car came with the relays as they are in the image.
If I swap the 17 relay with HELLA, the fuel pump stops working and the wipers work only at the highest setting the blower still doesnt work.

I bought a couple of fuel pump replays but these do nothing?? I have tested the relays for continuity and the click, they are both fine.
The fuse box seems fine with no corrosion all the fuses are also ok??

Can anybody help please!!

No 17 should not be in the fuel pump relay as you have found the pump runs as soon as you turn on the ignition without the engine running.

Will the car start with one of the fuel pump relays you have, the pump should not run until it's cranking over or some relays prime the pump before starting.

Bit more info on relay layout.

Thanks mark1gls for the links.

The car won't start with any of the other relays. It only starts with 17 in its current position which isn't where it supposed to be.
Are these new relays correct for this car? 
I'm not sure what to do next?

The topran fuel pump one is but they are usually poor quality and fall apart easily, not sure about the white one next to but it's not a VW replay.

where are on the country in case anyone near you can help with a known working relay?

NOT ALL FUEL PUMP RELAYS ARE CORRECT

There are known issues with them running all the time is one.

I'm going to order a couple different fuel relays and will you know how I get on.

If I manage to get the correct relay will this cure the blower and wiper problem too??

check your load reduction relay, verify that your fuse box hasn't had water migration, as the wipers and blower are on the Load reduction (X circuit in the schematics) line.

Load reduction relay 17 seems to be ok. Did a check and the relay clicks when powered.
The fuse box seems to be dry and no water migration. 

Relay 19 is however faulty( I have ordered another).

When I initially plugged relay 17 where is is supposed to be the blower came on for a second then switched off and I've not been able to get it on again. The fuses seem to be ok.

You have improper fusing there there isn't any 30A fuses except for A/C.

yours should be like:

Just a quick update.
I purchased another fuel pump relay HELLA 321-906-059/F  from heritage was abit pricey but the car now runs as it should with no continuous fuel pump running👍

I changed all the fuses to the correct amps the blower still not running I'm going to check the motor on the weekend.

The wiper works on the highest setting ONLY, I have another relay on its way and hoping that will solve that.

Thanks guys for all the help I really appreciate it.
I'll let you how I get on.

Another update.

The new wiper relay (19) works i now have wipers working in all positions.

The blower still not working I'm not getting voltage to the switch?

Any ideas as to where to go next from here??
