wiper problem

[Aussie John]

Wipers work fine on slow and fast and also self parking ok. the problem is the intermittent wipe is not working; I changed the relay but no joy. The question is does the intermittent wipe get power through a different fuse to the main wipe? Any ideas please.

On my 97.
F18 supply's the wiper motor.
F17 supply's Fast/slow/wash.
F15 supply's the intermittent relay.

Next to the steering wheel adjusting lever there is a small knob about 20mm in diameter, that when turned changes the speed of your intermittent wipers. If the wires going to this are broken then your intermittent wipers will not work.

I hate to admit it but I have had my car since 2004 and never noticed this knob before, maybe I should be banned from owning a tvr. Thanks for the help guys.

That's nothing, you'd be surprised how many people own Chimaera's and don't realise the roof comes off

& turns into a dangerous frisbee with a gust of wind

With the roof off the driver might end up like this

If you open up the plastic steering wheel cowl you'll find there's a white plastic connector for the rheostat, check here with your multimeter, with the cowl opened you can also check the function of the rheostat itself.

I've been fixing a dip/main beam switch issue today so took a photo for you.

The wires to the potentiometer are quite thin and can break at the soldered connections on the pot.
If you end up re-soldering these then it would be best to reinforce the joint with some sort of silicone or PU sealant.
