headlights wonky
 

Occasionally and currently, my headlights start flashing when in the 1,2,4 and brights positions(the control knob having positions 1-5, 3 being off...get it?), basically on any setting but regular headlights. The last time it happened, it was raining, this time I just had some work done at the shop(glowplug and malfunctioning antennae diagnostics/repairing). Any clues out there?
Thanks,
Alex

I'm not aware of any alarm system, though I think I read about one in the owners manual. The lights blink at a steady rhythm and while the brights bulbs function normally, the regular headlight bulbs flash. Incidently, my heating system seems to have stopped working as well!

allright, thanks.
