Simple.
A higher end voltmeter will usually have a capacitor test function. Or, you can purchase a capacitor tester.
The condenser in your car is basically a .25 uF capacitor. It should test at or near this value, and should show no leakage if good. Leakage is tested with an ohm meter (or a voltmeter with ohms setting).
When initially connecting the capacitor for leak test, the resistance (ohms) should be pretty low, but will charge quickly and show infinity (many megohms) and look like an "open circuit" within a second. if not, then it is leaky.
You can use a heat gun to heat the capacitor while under test and check to see if its value or leakage change with heat. If good- Its value should stay within 5%, and should never show signs of leakage regardless of temperature.
