Upon ignition the following items may not work in unison: the rear window defroster, the heater, the blower, the turn signals and the back up lights. (The turn signals will light up but will not flash).

NOT affected when the other items fail are the dashboard lights, the flashers, the headlights, tail lights, or the high beams. They continue to work just fine.

This failure does not take place once the car is running. It only occurs upon ignition, and then maybe just once out of every five starts. This issue began a week ago.

Note: For the past 3 years I average less than 100 miles per month.

What is the problem? Generally speaking, where should I go for electrical repairs on an older car?

Thank you,
