What did the "smoke" smell like? I suspect you have a bad heater core, in
which case the smell would have been of hot coolant, not a burning smell.
If that is your problem, you need to replace the heater core. This is not a
fun job, but it is one you can do, if you have the FSM to guide you. Most
radiator shops will take your old heater core and replace the core part,
making it good as new - it will probably cost under $100 if you do the R&R
yourself.
