550 Wiper Relay

Should be on left side in footwell,upside behind the panel. At least on a -97 it was

On our car the earth pin had broken off from the soldering. Easy fix.

 

My wipers are also not working right. Sometimes it works right away, but most of the times I have to switch to warp speed and then back again to normal speed or interval. Sometimes it doesn't work at all. I found out it is the handle on the steering column that is not OK. Fuse is still OK. Handle is still available.

The fuse for the wipers is the 4th from the left (20A). That is in my EU spec. 550.

i have this issue - dodgy wipers, cannot find the relay...... RHD car. Any tips ? Or does Qavion have one of his useful wiring diagrams ? many thanks

 

550? Sorry, I don't know where it is. On a RHD car, it could be anywhere. Judging by the online parts manuals, it's under the dash somewhere (part 11). i.e. if you mean the control module. There is no regular relay.

Since most of the wiring is mirrored on a RHD car, I would check under the dash on the driver's side.

 

if it helps someone, I found it today. I traced the wires back from the motor in the engine bay, and realised it must be inside the cover next to the gas pedal on a RHD car. I got the cover off (which was a pain due to a seized lower screw and me not realising it was held on at the back by the 2 screws in the metal plate) and worked out which bit it is due to the colour of the wires. As luck would have it, thats as far as I got as the wipers worked perfectly today, but at least locating it will assist with future diagnostics......

 

Thanks, Matt. So on a right hand drive car it would basically be near the right hand engine ECU.

 

yes, bang on, right next to it

 

Thanks for the confirmation, Matt. I don't have a RHD wiring diagram, but I'll add a note about location to the USA diagram.

(See "92")

(EDIT: disregard... The parts manual shows a horizontal mounting for the USA cars, so I suspect it is not near the ECU. I'll have to re-edit the diagram).

 

if it helps further the harness in the engine bay joins onto a much thicker loom when then all goes through the bulkhead and into the footwell. There's quite a few other components down there - let me know anything else you want me to check while it is all apart.....

 

If you could get a picture of it in location, that would be great. It would be an aide-mémoire (at least for me) should someone ask this question again.

 

here you go - its the larger of the two black modules - the one without the big "BOSCH" on the top, right under the purple wires....

Excellent photo, thanks.

Now I have to do some sleuthing to figure out what that mysterious white plug is with the purple-black and green-black jumper wires on it.

And the Bosch relay.

 

I think I've figured it out. The Bosch relay may be the starter relay (controlled by the immobiliser). This has some white, grey and black wires on it, one of which goes to, I suspect, that mysterious white jumper plug (which is connected to the immobiliser). The plug is numbered "324" in the wiring diagrams.

As they say, a picture is worth a thousand words

 

Added some notes to my 550 Alarm wiring diagram regarding the starter relay and jumper plug on RHD cars...

Ian- Here it is as a pdf, a bit easier to work with and easily expanded.
