My wipers have been getting progressively worse I now have stop ,stop, very slow and stop. Seriously though slow works ok but 'fast' needs a push to get it going before stopping again, it usually sorts itself out with use but I fear this may be the time for a rewind, just thought I would try and get some ideas before pulling it out also can anyone advise me if its an mot fail ?
I would first suspect electrical connections particularly earths, then lack of or dried up lubrication. The motors themselves are quite resilient as they are designed to survive being stalled for lengthy periods.
I would'nt think they would wear out on a TVR as they have a habit of hiding in garages in the wet.

Hi Mikel. If your motor is gone you might find this of help. Wipers on my S1 were poor and wouldn't self cancel. Took the motor off, stripped it and found it damaged. On my car (1988) the wipers are crank operated rather than spiral wire. It appears from 'Steve Heath' that '88 was a change year but I have heard of a variety of systems being fitted. Anyway mine had an AC DELCO motor. A visit to my friendly factor (who is becoming an expert on TVR parts problems!) indicated that it may have been Vauxhall sourced. That looked promising at first but all the Vauxhall ones we could find were the opposite 'hand'. Time to visit the breakers (again!). Couldn't find any Vauxhall that fitted but a lucky break and I spotted a Peugeot 405 with the wiper motor hanging out. Same hand, same size, same fitting points! Made by Valeo and not identical but very close. Half a dozen 405's in the yard, all the same. £10 (Vauxhall quoted £110 +vat for a wiper motor!). See pics

The spigots for mounting the crank are not quite identical and I had to be a little careful mounting it to ensure the crank arm cleared the mounting bolts but it was quite easy really. One word of warning though, the wires are not arranged in the same order. The correct connections are S1 wire blue/green goes to red on the wiper, black (earth) goes to black, green/pink goes to blue, red/green (permanent live) goes to white, brown/green goes to grey.
Now working perfectly (or at least, as well as TVR wipers can be expected to work!). Just as well as 'her' first drive was in the wet!

Sadly I couldn't access the photos (probably because my phone has limited internet ) I will however head to the scrap yard, thanks for the advice . Did you have to remove the dash or just pull it forward ? Or perhaps its Easyer to get to than it looks at a glance , do you have the intermidiate setting now too ? . I have also been able to establish that the fast setting does not do more than a few inches of travel even after a push thanks everyone again
I didnt have to move the dash at all, the motor is above the passenger footwell and awkward rather than difficult to get to. I didnt have to take off any of the mechanism. I seem to remember that I might have had to remove the passenger side trim panel on the transmission tunnel to get enough slack in the wires. The Pugeot couldnt be easier to get at, rip up the louvred panel between the screen and the bonnet and there it is! Dont forget to cut off enough wire to connect to as the old TVR wiring plug wont fit and you have a bit of wire splicing to do! Good luck, let me know how it goes.
Hi Mike,
I spent ages typing out a technical treatise on my own wiper problems, only to find the forum had gone down and I've lost it all. Computering is not my forte.
Anyway, my 1987 S1 wipers were wobbly on the passenger side and both v. stiff & slow, sometimes needing a push to get them moving. Investigation showed both spindles were seizing in their bearing tubes, and the bearing tubes were trying to rotate the mounting/spacer ally bushes that retain the wiper spindle assy's in place on the scuttle. The bushes are TVR factory fitted, made from 3/4" i/d ally tube cut diagonally to preseht the wiper arm at the correct angle. The pass. side bush had split in half as the seized spindle was trying to flex the bodyshell GRP, not good.
I stripped out the whole spindle assy's, driver's side first as it's more accessible. The spindle is retained in its bearing tube by a small circlip, and there are shim washers and an "O" ring seal.
I had to use the vice to get the spindle out of the bearing tube, it was very tight. Plenty of Plus-gas helped. Cleaned up with emery and an internal fine wire brush, then assembled using copper grease (Moly grease alternative).
I made up a new inside bush from a long brass 3/4" BSP barrel plumbing connector, cut across diagonally with a hacksaw using the broken bits as a pattern, and filed to finish. Assembled back on the scuttle using a generous seating of JB Weld epoxy metal inside & outside the scuttle where the bushes sit.(*Mask up the outside area first) Allow full curing time before fitting wiper arms.
Repeat on the passenger side, access is more difficult, but no need to remove dash. Just make sure wiper motor is isolated, it's v. powerful & won't stop for fingers or wrists!
If pics would help clarify, I've got some on my phone I could email you if you PM me your email address. I dunno how to post pics on here.
Hope this helps, Glen

Thanks for all your help , to be honest I have done very little more , except fiddle with the electrical conections , I have established that contrary to previous posts mine is a lucus motor, any ideas ??????? Also was able to confirm that slow works fine so figure the fault is not with the motor itself , what is it that effects the speed , is it just a stronger currant ?

Use Word to create your piece then copy and paste into PH. You also get the benefit of spell-check this way as well.
Mike, just disconnect the wiper drive from the spindle on the driver's side - it's a ball % socket that you can prise apart with a screwdriver. Then see if you can easily move the wiper arm manually over the full range. Mine wasn't used to going out in the rain, and the wipers had seized due to lack of use. I think you may have the same problem I had. See my earlier response and let me know if you want me to send pics.
MIke, there are two power inputs to the motor, one for low speed and a second for high speed. There was a pretty dicy connection block on mine so you may only have power to slow speed. With care, try a direct connection from the battery and see if touching the right terminal gets the motor going. If it does then you have wiring to trace (could just as easily be at the switch end). If it doesnt then the motor isnt working properly and may have to be changed.
The fact that yours is a lucas motor, and mine AC Delco may not make any real difference. If you have to take it out it is likely that there are only minor differences in mountings or connectors and the Peugeot one can still be made to fit. Apart from a few of the very early cars (less than 50 I believe) all those with linkage drives have the same linkage and the motors should have only minor differences.
If you get stuck working out which wire is which, get back to me, I may be able to dig out the notes I made at the time, I should have filed them!
