Intermitant motors should be replaced. From experience, relays and transformers rarely go out. It is usually the motor that burns out and it usually does so quickly when at life's end. Take the time to check all of your wire connections-hours can be spent diagnosing a vacuum only to find out it was a bad connection.ntermitant motors should be replaced.

If the alternator is bad, your car or truck will eventually die out again as the battery is not re-charged. Get a good-quality voltmeter or multimeter and test your batteryâs state of charge. The voltmeter should read around 12.6 volts with the engine off and 14-15 volts when the engine is running. If voltage is below 13.5, thereâs a good chance the alternator is not keeping up with your batteryâs charging needs.
