The timer is activated from the wiper switch 'intermittent' position and closes the relay once every 5 seconds, sending power to the wiper motor. Incorporates an output for supplying +12V to the wiper motor park switch which shorts the motor at the end of the wipe cycle, bringing the blades to an immediate stop in the 'park' position.

Used to repair early Toyota wipers. Same relay function as stock. Worked awesome

Intermittent rear wipe for Citroen C1
25 September 2022  | 

The C1 has a single speed rear wiper which is constantly on or off (not very useful). Simple, single speed, motor - what to do?

Using this relay with an automotive relay (4 Pin - Normally Open Contacts SPST) provided the intermittent earth signal required for a 5 second intermittent wipe. Works very well - even managed to tap into the (previously redundant) rear lo speed setting on the Prius wiper stalk I'd installed. Total cost of the solution is about £30 plus some cable and spade connectors. Would recommend this relay

Great unit

Works great. However, don't accidentally put +12V on pin 1 as it will kill the relay. I found out the expensive way.

Very keenly priced; does what it says on the tin so to speak.
Worked first time in accordance with the wiring details, no problem.

Have used before to adapt a classic car's wipers to delay. Recommended item.

Would be better if there was a remote "pot" to vary the time delay maybe up to 20 seconds. I had to use the timer to control a seperate relay (1 n/o & 1 n/c contact ) in order to get the wipers on my ser 2 e-type, they work fine but could do with a longer time delay

Wiper Timer Relay

I was using this relay to add intermittent wipers to my Triumph Herald, as the old Lucas wiper motors on these cars have a permanent live and are switched on the negative side I couldn't wire as per the instructions. To overcome this I used the timer relay to switch a standard 4 pin relay and this works well.

One other issue is that the relay could do with keeping the circuit open slightly longer as it's a little quick for these old wiper motors when initially turned on.

These 2 minor issues aside it's a neat solution that works well and is reasonable priced compared to other similar solutions. I would happily recommend the product.

does what it says on the packet!

really appreciated 12v planet giving a fulling wiring diagram for fitting - so many after market suppliers don't. Followed the diagram - fitted in 20 minutes max - works straight out of the packet - timing just about spot on 5 secs - really pleased
