I parked my car for approximately a year. Put in new battery. Car turns over and starts, but none of power options work windows, locks, alarm, etc.

Have you checked the fuses yet?

No. I didn't know you could blow a fuse just by hooking up a new battery. But I will do that next and let you know.

Thanks

The fuses are all good. at first I said the car would start, now it turns over but won't start and I still have no alarm, power windows, locks, seats, etc. There must be some way to reset the system.

You didn't happen to hook up the battery backwards for a second did you? If not there must be a main relay that got burnt up, there is a main power supply that is not working. I tried looking up the wiring diagram but Mitchell1 doesn't seem to have the info we need. Use a test light and start probing around.

Please let us know happens so it will help others.

Best, Ken
