Hi Eddie..
was it flashing from being too hot, or from the pressure bottle level being
low ?

what year is it  ?   early ones are a little odd in the red LED department.

Did you check the coolant level ?
What was the temp needle showing when the light was flashing  ?

One doesn't usually especially think of the thermostat because ...
usually when they fail it's in the 'too cool' direction.

'dim' ?
usually it's pretty bright, being an LED.

It always helps to say year, model, and version.
there are several kinds of vanagons.

Subject: flashing red light

daughter got in the vanagon this evening and saw a dim flashing red light on
the heat gauge. The van seems to be running fine though, and i installed a
new thermostat 2 years ago, and I don't think it should go bad that fast.
Any suggestions.
thanks
