Mercedes Benz repair: glow plugs for 1980 240D, glow plugs, glow plug

Question
We had a cold spell in Denver.  The glow plug light started
blinking after start-up.  Shortly after that the car won't start,
even in warm weather.  The glow plugs probably have less then
20,000 miles.  It is as simple as replacing the glow plugs.  Is that
replacement something a novice can do?
thanks

Answer
Check the strip fuse in the glow plug relay.
If the fuse is OK, there is a chance the relay or glow plug wire harness is bad.

Glow plug testing and change is not difficult read through the following links in this thread.
