    ...and the smoke stops when its off. i turned on the fan, pulled over and popped the hood, nothing smoking inside the engine compartment. it smells like an electrical fire...ITS HOT OUT. I need my AC...also starting today i gotta pick up the work crew at the designated parking lot and drive them to and from the jobsite area...i gotta have the ac runnin', or else this may follow me around like a black cloud the rest of my career...LOL.
    Thanks,
    patrick

    Hey, welcome to the site. Is it Patty, or Patrick? Hmmm, I'll just use Pat.

    Pat, that smell is probably the resistor assembly that lets you change blower motor speeds (high/med/low) The engineers will design it so the resistors are mounted in the air flow so it will keep them cool; but, when they decide to go, they are going to burn up. A new assembly is the only answer.

    many with this year had the blower /relay/resistor connector burn up.. poor design.. could be a recall/tsb about this.. under dash behind the glove box open it up at the blower motor the electrical connector should be melted...

    check at auto part store may have this..connector
