99 volvo S70. When I start my car (either turn it to start or physically start it, the power windows/radio/blower and wipers do not start for right at 2 minutes. Also the SRS and service engine light come on. The lights/blinkers/door locks and gauges/clock all work from the get go. Once the accessories start, the SRS and service engine lights go out.

I have replaced the ignition switch.

If I turn the car off and start it right back up, everything works fine. If it sits 10 or 15 minutes, the exact problem occurs.

 

Check all the terminal connections under the hood including the main power wire in the under hood fuse box.
