1. Check voltage on the DIC/HVAC and HVAC CTRL fuses for losing voltage when the problem is occurring.

2. If the fuses lose voltage during the problem, go to the Orange wire at pin C6 in connector C201 at the base of the steering column. This wire feeds the above fuses, check for a loss of 12 volts during the problem.

3. If the voltage is low, replace the ignition switch.
