Good work on sorting the blower motor :thumbup:
It is quite common to find 4ws/abs bulbs removed so that they can get MOT rather than sort the problem.
Ive got to say your doing a fine job of sorting out all these issues - pain in the arse sorting out all these bodge jobs from previous owner(s) :clap:
I have some spare fuel/temp guages if you get stuck also control box for central locking etc

When I bought mine, some kebab had removed the 4WS bulb too.

Took me longer to replace the bulb than to fix the actual fault :crazy: , which was a resoldering of dry joints in the 4WS ECU.

17 years later it still works like a charm.

I'm not really sure how far into this car I should go. I could spend loads getting it sorted only to remove the sill covers and find its rotten through.

I kind of get the feeling I should spent a few hundred pounds getting silly stuff fixed and give it a few years on road. Every time I fix something I find two more broken things!

After reading through the diagrams I think I can just wire the door solenoids up, interior lock/unlock switch and a remote central locking box from ebay!

Trying to sort out a glass sunroof next and I've noticed a strange clunk develope from the rear passenger wheel, will need to take a look at that!

A couple quick questions. The manual says I need to check the abs system when the car is still. But the light only turns on after I go down the road a little (I assume that means it's a wheel sensor), is it still just a case of paper clipping the same plug after I stop?

The engine seems to hunt a lot once its at idle, but no check engine light. Seems to run perfect. Any common failure points?

The clunk from the rear wheel could be sticking of caliper or pads
Hunting at idle will probably be the iacv- this is atta to the throttle body - just unbolt it and clean it out with some carb cleaner - no need to disconnect the coolant lines. :)

The idle has more or less gone away, probably from. Just using it.

I found the Clunk to come from the rear upper control arm bushings one of the ones that goes to the body, does anyone know the part number of the bushings?

Dont know the part number - dont think there is one as normally honda would replace the whole arm. The end link with bushing is same front and rear so you could replace with one of these used parts on ebay:
https://www.ebay.co.uk/itm/223954907931 ... SwRhFb3gRa
should be easier than taking the link out and having to push the bearing out and then replace it.
The other suggestion is to get some tiger seal and use it to shore up the existing bushing.

I had a look at the diagrams and it only lists the whole arm, and they are expensive!

That looks good! I just need one, I hope that is the Clunk as it's the only loose part I can find in the suspension! Will order it up now.

Changed out the rear bushes. It's much better but still has a slight Clunk. I can live with it!

Abs issue is the rear right sensor, it has 16k on it, when It should be around 1.3k... Does anyone know where I can get one?
