1979 Sunny Coupe with SR20DET - Update on page 27

Are you looking at just getting a universal pump or a completely new washer bottle and pump?

I've used universal pumps now problem but they don't always fit the old reservoir so you need to run some right sized pipe from new pump to hole in old bottle and depending on the wiring you might need to replace the connectors.

Also used an ebay universal bottle/pump recently and they come with everything you need - may be just as easy replacing the whole lot.....

try reversing the connections on the pump and giving it a bump. Sometimes frees them up.

Went 100% ghetto with a squeezey water bottle. I can look at the electrics better at the weekend.

Horn on the dash is fine .
Just label it as such .

Not sure 'being in an accident , leaving us liable' is in the reasons for rejection list

That's wrong & it gives 'proper' mot testers a bad name .
We have a guide to follow , that everyone can see , that lists how things are tested & what would fail .

We see alot of cars that have failed for no real reason .

Do you have a local council mot station near you ??
A bit more expensive , but totally unbiased .

I'd be demanding my money back and reporting them to DVSA?

Audible warning (horn) RfR:

1. The horn control missing, insecure or not readily accessible to the driver.
Note: Inform the driver if the horn is insecure.
2. The horn:
a. inoperative
b. is not loud enough to be heard by another road user
c. is a gong, bell or siren
d. has more than one tone
Note: When operated, a two or more tone horn automatically produces a sound which alternates at regular intervals between fixed notes.
e.fitted to a vehicle first used on or after 1 August 1973, emits a sound which is:
not a continuous or uniform note 
harsh or grating.

Wipers and washers RfR:

1a. A wiper or washer control missing or inaccessible to the driver
b. a wiper does not continue to operate automatically when switched on
c. a wiper installed for the use of the driver does not operate over an area of the windscreen large enough to give the driver an adequate view of the road (through the windscreen) to the left and right sides of the vehicle, as well as to the front.
2. A wiper blade insecure, missing, or in such a condition that it does not clear the windscreen effectively to give the driver an adequate view of the road (through the windscreen) to the left and right sides of the vehicle, as well as to the front.
3. The windscreen washers do not provide enough liquid to clear the windscreen in conjunction with the wiper(s).

For the horn what about using a foot operated dimmer switch?

Or just find a better MOT station.

P.

Reading back to find the issue with the horn. Might make a good case study for that thread (been in holiday and largely banned from the internet as I can't resist working). I've no idea what you should have for a horn, is there a button in the steering wheel that should be w horn?

In either case neither are valid reason for a fail, and require contesting. Certainly no more an issue than a horn on the end of the indicator stalk (moggy minor for example). Washers are just a means of getting fluid to the windscreen, and your method is no different to the factory fitted manual pumps (again, moggy minor).

I'm bumping this for my own post SEMA motivation.

Going to have another go at wiring up the horn and the washer. If not it'll go to another MOT place on Friday, and then (with an MOT hopefully) somewhere more competent that can do wiring (and they can put the fan switch in place too then).
