HELP! Two days ago I had the defrost on high heat with the window and mirror warmer on as well. The Recirc was on with the light on and the A/C was off with its' light on. It was foggy and I needed to clear the windows. After about 10 min of this the instrument panel started to smoke and I smelled burnt electrical wire. Smoke rose from below the recirc and A/C lights as well as the fan switch. Fortunately I arrived at work and shut the engine down and shut everything off. Now the lights do not illuminate (before the both were on, as they should be even with the fan off). I have not tried the fan but the rear window and mirror heater works. There is STILL a smell of burned electrical wire in the car even after hours of being shut off. What is causing this? Why don't the lights on the Recirc and A/C work? Isn't there supposed to be a fuse that blows to protect against this?

Please help this is a serious problem.
