01 LeSabre power lock/lighter/trunk stopped working

[albertge]

Hi guys, I have a 01 LeSabre which has 109XXX miles, last week I forgot my key in the car so I used the spare key opened the door, I knew I could not start the car with the spare key but I wanted to try to start it (stupid stupid idea...). As expected, the key could not start it and I found my power lock (on both front doors), cigar lighter outlet(both of them) and trunk open button stopped working at the same time after that...

The strange thing was the power window, power seat and everything else were working well... I checked the fuses in the engine compartment and under the rear seat but they were both fine...

I was wondering whether else could result in such a problem...

Please let me know if you have any idea what could result in this... Thank you!!!!!!
