Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Works properly when i run a parallel power wire from fuse 1 direct to bulb connector , so very likely a break in that original wire.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Try as I might, I can not find in my relay panel the relay for the headlight washer system on my RHD 1981 924 Turbo. Relay # 928 618 111 00. Can someone please enlighten me? (I can not turn off the headlight washer system when the headlights are raised - finding and checking the relay seems like a sensible first step) Thanks in advance DaveO

POST 2Original post

Hey @DaveO90S4, If there is one, it should be the 4th one up from the bottom. Cheers

POST 3 / ORIGINAL POSTEROriginal post

Thanks for that Dreamr. I will have to look harder! In the image you kindly attached there are clearly 2 rows of relays. I can only see on my car one row of relays - the row with the horn relay - and not the top row. But it is very evident that in this car's past someone has been playing with wiring:- looks like lots of remaining wires and in-line fuses for a now non-existent non-factory stereo amplifier. I will keep hunting. Not that I need the headlight washer system, but I do need to stop it working all the time whenever the headlights are on. Thus far I have simply pulled the plug off the motor. That works and is the quick fix. But it is not the 'right' fix. Cheers DaveO

POST 4 / ORIGINAL POSTEROriginal post

Fixed. Thanks. I could not find the 928xxx relay because someone gad put a vw 111xxx relay in instead. I have put in a typical ‘normally open’ 4-pin ‘type 53’ relay (same as horn relay). Washers work properly now, but can be operated with headlights down (who would ever do this, and it wouldn’t matter if they did) and does not have a time limit (but the switch is spring loaded and who would ever drive along holding that switch in yhe on position for any extended time). So I will call this a ‘win’. Now to find reason for no low beam power to lh headlight. Works properly when i run a parallel power wire from fuse 1 direct to bulb connector , so very likely a break in that original wire. I’ll trace it from each end and see what I find Cheers DaveO
