308 intermittent wipers

Hi All,

Had my 308GTB out today and got caught in a rain shower. With the wipers on the first speed, they work normally for about 5 strokes and then have a 'rest' for a second or so, followed by a click and another 3 or 4 strokes. This keeps going in this pattern. On second speed, they work normally.

I don't think vetro's had intermittent wipers as standard so am wondering if its a sticky relay or similar.

Any ideas appreciated.

I'll bet you that the linkage from wiper motor to wiper has a broken or loose joint. Think of a rotating cam that slips sometimes and catches sometimes. other possibility is worn wiper motor but I would not expect that. good luck and please let us know what it was when you find it. Bill

Hi Bill
Had a look at the linkage today after removing the trim around the spare tyre.
I sprayed the two ball joints (?) under the wipers with penetrating fluid which made a big difference. Tested by lifting up the wipers to the off windscreen position and turning them on. The more they ran the looser they got.

Hopefully thats a fix - thanks very much for the suggestion.

Usually when I go out I turn on and run everything - aircon, headlights, windows, horn, to keep it all loose and working. I forgot all about the wipers though. Maybe I should run them when I wash the car to make sure they dont tighten up

I wounder if the nut that attaches the wiper motor to cam that moves arm is loose or maybe 'owled' out a little. Maybe the click you're hearing is allowable slippage when arm binds or possibly loose? Do you get alot of dust there? I live on a gravel road so I try to use graphite or other lubes that don't attract dust as much on linkages like this. Bill

On my 77 the stalk lever in the up position is for intermittent wipers and in the down position it is regular wipers speed (slow speed). There is a high speed switch on the console for faster operation. Oh I have only used my wipers twice in the 10 years I have owned the car. I don't take it out in the rain. I do run all of the electronics as a habit when I ride.
