Intermittent Things: Cruise Control, Intermitent Wiper and Turn Signals

[RobertFini]

There are several functions that have lately begun working intermittently on my 1994 E320T.

The cruise control typically works perfectly, holding a very steady speed and keeping me out of the limelight when tooling down the highway. Unfortunately, it occasionally stops working for no apparent reason but will come right back to life when I turn the ignition off and then back on again (if on the highway, I'll do this while still rolling by kicking the car into neutral, turning the key off and then restarting right away). Once this happens and I "reboot," it's usually fine for the remainder of the trip.

The windshield wiper is another thing that's got me scratching my head: the intermittent setting sometimes works, sometimes doesn't (lately more not), but the two steady-on settings work just fine all the time.

Finally, the turn signals are acting up as well - sometimes working, sometimes not, with no apparent pattern. Thanks in advance for any insight.

I can't find any connection between these three issues, so they might be randomly unrelated, or maybe there is some common element that I'm not seeing.

Best Regards,
Rob
