Hi Guys,

Anybody has an idea what my car's problem is?

While driving, once i flash the high beams, the doors' power locks would open, and the car would go into something that feels like an engine break.
If the radio is on, it will stutter.
After the flash or after the high beam is fully turned on, everything's normal again - except my doors are now unlocked, my dashboard clock is reset, and my car alarm is set back to default settings (aw!).

It does not always happen; but once it does, it goes on for the duration of the trip. It can happen in daytime (no lights) and at night.
I'm beginning to be worried because it's happening more frequently now.

Nothing has been replaced recently. using 55/65w H4 on a 2002 city

With a fluke vmm I'm getting:
~13.8V with engine running / lights on / ac on / radio on
~12.7V with engine and everything off

thanks in advance!
