blower control and shifter lights off
 

Hi, I have this odd problem.A week ago my transmission broke so I gave it to the shop to replace it.After I got my car back I notice that the controls on the blower pannel(A/C,heating seats and all this)plus the lights on the shifter box are off and dont work at all,the only thing that works is the lighter.I check the fusebox all ok, tried a new unit not working,so I am wondering what can be the problem.The shop that fixed my trany is saying that there is nothing they removed that can be causing this problem but I still doubting this.I am wondering if there is any ground cable or anything that they might have disconnected and forgot to connect.I really need help here cause summer is approaching and it will be very difficult for me to cope with the hot weather this way,any advice is highly appreciated.Thanks :)
