here is what just happened to me. so this morning i was walking past my car going out the garage door, when i notice that hvac/stereo is lit up. ? ... check and see if i left the ignition is on. nope it was off. checked to see if it starts, it does but is cranking a little slower than normal. wtf!! also i cant shut it off or change temp settings at all. well i went to work came home and the car is dead. wtf again!!! i just got done jumping it to find that it still has the same prob, so i took the whole thing out. what do you guys thinks wrong? it's toast or what. side note, does anyone know where i can get a new unit the cheapest, the wife is going to freak! thanks in advance!
