12vdc Timing Switch

Is there a perpetual timer available where a 12v appliance can be automatically turned off and on at a regular interval.

If you only need a few seconds, do a google search on "Game Timer". These are set up to run for a period of time every day. Can possibly be modified for longer runs.

If you can use a soldering iron, you could try and build your own circuit using an IC555 see link below

The 555 Timer IC

If you would like any help understanding the circuit you could send me a PM and I would be happy to help

This should fit the bill, unless the load is more than 12 amps... Fuel System Maintenance Timer / Controller

Check the tech specs for the DC switching capability of the timer recommended by MarkJ to ensure they are sufficient for your load. DC switch capability (in amps or horsepower) is dramatically less than the switch's rating for AC loads.

I've used these Artisan - 2600 Repeat Cycle Timer to control an 8 amp/ 12 VDC load.
