Volvo 700 » Ignition Electrical Switch

Do your heater motor, wipers, or radio seem to have a mind of their own when it comes to consistent reliability? The most common problem is the electrical switch behind the ignition key. The contacts inside wear away and the accessories can come and go intermittently. You can test your switch when it fails by turning the key counter-clockwise (not so far as to turn off the ignition) and if the above-mentioned accessories begin working the switch needs to be replaced.
